What factors should be considered when selecting eye bolt screws for specific applications?
When selecting eye bolt screws for specific applications, several factors need to be considered to ensure the appropriate choice that meets the requirements of the application. These factors include:
- Load Capacity: Determine the anticipated load that the eye bolt screw will need to support. Consider both the static and dynamic loads, as well as any potential shock or impact loads. Choose an eye bolt screw with a load capacity that exceeds the expected loads to provide a safety margin.
- Material Strength: Evaluate the strength properties required for the application. Eye bolt screws are available in various materials, such as steel, stainless steel, or other alloys. Consider factors such as tensile strength, yield strength, and hardness to ensure the selected eye bolt screw can withstand the applied loads without deformation or failure.
- Corrosion Resistance: Assess the environmental conditions in which the eye bolt screw will be used. If the application involves exposure to moisture, chemicals, or corrosive elements, choose eye bolt screws with corrosion-resistant materials or coatings, such as stainless steel or galvanized steel, to prevent premature corrosion and maintain the integrity of the screw.
- Thread Type: Consider the type of thread required for the specific application. Eye bolt screws may have different thread types, such as coarse threads or fine threads. Coarse threads provide quicker installation and higher resistance to vibrational loosening, while fine threads offer finer adjustments and increased holding power.
- Attachment Point: Determine the method of attachment and the hardware that will be connected to the eye bolt screw. Consider the size and shape of the eye to ensure compatibility with the intended hardware, such as ropes, cables, or chains. The eye should provide a secure and properly fitting attachment point to minimize the risk of slippage or failure.

It is important to consult with industry professionals, engineers, or manufacturers to ensure that the chosen eye bolt screws meet the specific requirements and provide a reliable and safe solution for the intended application.
Can you explain the different types of eye bolt screws available in the market?
In the market, there are several different types of eye bolt screws available, each with its own design and specific applications. These variations in design make eye bolt screws suitable for a wide range of uses. Here are some of the common types of eye bolt screws:
- Regular Eye Bolt: Regular eye bolts are the most basic type of eye bolt screws. They feature a straight shank with a looped eye at the end. The eye is typically circular or oval-shaped. Regular eye bolts are used for various applications that require a simple and reliable attachment point.
- Shoulder Eye Bolt: Shoulder eye bolts have a shoulder or collar between the shank and the eye. The shoulder provides additional support and prevents the bolt from pulling through the attachment point. Shoulder eye bolts are often used in lifting applications, where stability and load-bearing capacity are crucial.
- Machine Shoulder Eye Bolt: Machine shoulder eye bolts are similar to shoulder eye bolts but have a smaller shank diameter relative to the eye size. They are specifically designed for use with machinery, where space constraints or specific mounting requirements exist.
- Lag Eye Bolt: Lag eye bolts have a lag screw thread on the shank, allowing them to be screwed directly into wood or other materials without the need for a pre-drilled hole. They are commonly used for attaching ropes, cables, or hardware to wooden structures, such as decks, fences, or playground equipment.
- Welded Eye Bolt: Welded eye bolts have a welded eye instead of a looped eye. The eye is permanently welded to the shank, providing a strong and durable attachment point. Welded eye bolts are often used in heavy-duty applications, such as construction, manufacturing, or rigging.
- Swivel Eye Bolt: Swivel eye bolts feature a swiveling eye that allows for rotation and movement. The swivel action helps prevent twisting or tangling of ropes or cables. Swivel eye bolts are commonly used in applications where dynamic or multi-directional forces are involved, such as lifting or rigging operations.
- Shoulder Nut Eye Bolt: Shoulder nut eye bolts have a shoulder between the shank and the eye, similar to shoulder eye bolts. However, they also feature a nut on the shank, allowing for adjustable tension or positioning. Shoulder nut eye bolts are often used in tensioning applications or for attaching hanging objects that require precise alignment.
The choice of the appropriate type of eye bolt screw depends on the specific requirements of the application, including load capacity, attachment method, space constraints, and functionality. It is important to select eye bolt screws that meet the necessary specifications, such as load ratings, material strength, and corrosion resistance, to ensure safe and reliable performance.
When using eye bolt screws, it is essential to follow manufacturer guidelines, industry standards, and applicable safety regulations. Proper installation, torque values, and regular inspections are necessary to maintain the integrity and reliability of eye bolt screw attachments.

Screw Shaft Types
A screw shaft is a cylindrical part that turns. Depending on its size, it is able to drive many different types of devices. The following information outlines the different types of screws, including their sizes, material, function, and applications. To help you select the right screw shaft, consider the following factors:
Size
A screw can come in a variety of shapes and sizes, ranging from a quarter to a quarter-inch in diameter. A screw is a cylindrical shaft with an inclined plane wrapped around it, and its main function is to fasten objects together by translating torque into a linear force. This article will discuss the dimensions of screws and how to determine the size of a screw. It is important to note that screw sizes can be large and small depending on the purpose.
The diameter of a screw is the diameter of its shaft, and it must match the inner diameter of its nuts and washers. Screws of a certain diameter are also called machine screws, and they can be larger or smaller. Screw diameters are measured on the shaft underneath the screw head. The American Society of Mechanical Engineers (ASME) standardized screw diameters in 3/50-inch to 16 (3/8-inch) inches, and more recently, sizes were added in U.S. fractions of an inch. While shaft and head diameters are standardized, screw length may vary from job to job.
In the case of the 2.3-mm screw group, the construct strength was not improved by the 1.2-mm group. The smaller screw size did not increase the strength of the construct. Further, ABS material did not improve the construct strength. Thus, the size of screw shaft is an important consideration in model design. And remember that the more complex your model is, the larger it will be. A screw of a given size will have a similar failure rate as a screw of a different diameter.
Although different screw sizes are widely used, the differences in screw size were not statistically significant. Although there are some limitations, screws of different sizes are generally sufficient for fixation of a metacarpal shaft fracture. However, further clinical studies are needed to compare screw sizes for fracture union rates. So, if you are unsure of what size of screw shaft you need for your case, make sure to check the metric chart and ensure you use the right one.
Material
The material of a screw shaft plays an important role in the overall performance of a screw. Axial and central forces act to apply torque to the screw, while external forces, such as friction, exert a bending moment. The torsional moments are reflected in the torque, and this causes the screw to rotate at a higher rate than necessary. To ensure the longevity of the screw, the material of the screw shaft should be able to handle the bending moment, while the diameter of the shaft should be small enough to avoid causing damage.
Screws are made from different metals, such as steel, brass, titanium, and bronze. Manufacturers often apply a top coating of chromium, brass, or zinc to improve corrosion resistance. Screws made of aluminum are not durable and are prone to rusting due to exposure to weather conditions. The majority of screw shafts are self-locking. They are suited for many applications, including threaded fasteners, C-clamps, and vises.
Screws that are fabricated with conical sections typically feature reduced open cross-sectional areas at the discharge point. This is a key design parameter of conical screw shafts. In fact, reductions of up to 72% are common across a variety of applications. If the screw is designed to have a hard-iron hanger bearing, it must be hardened. If the screw shaft is not hardened, it will require an additional lubricant.
Another consideration is the threads. Screw shafts are typically made of high-precision threads and ridges. These are manufactured on lathes and CNC machines. Different shapes require different materials. Materials for the screw shaft vary. There are many different sizes and shapes available, and each 1 has its own application. In addition to helical and conical screw shafts, different materials are also available. When choosing material, the best 1 depends on the application.
The life of the screw depends on its size, load, and design. In general, the material of the screw shaft, nut body, and balls and rollers determine its fatigue life. This affects the overall life of the screw. To determine whether a specific screw has a longer or shorter life, the manufacturer must consider these factors, as well as the application requirements. The material should be clean and free of imperfections. It should be smooth and free of cracks or flaking, which may result in premature failure.
Function
The function of a screw shaft is to facilitate the rotation of a screw. Screws have several thread forms, including single-start, double-start and multi-start. Each form has its own advantages and disadvantages. In this article we’ll explore each of them in detail. The function of a screw shaft can vary based on its design, but the following are common types. Here are some examples of screw shaft types and their purposes.
The screw’s torque enables it to lift objects. It can be used in conjunction with a bolt and nut to lift a load. Screws are also used to secure objects together. You can use them in screw presses, vises, and screw jacks. But their primary function is to hold objects together. Listed below are some of their main functions. When used to lift heavy loads, they can provide the required force to secure an object.
Screws can be classified into 2 types: square and round. Square threads are more efficient than round ones because they apply 0deg of angle to the nut. Square threads are also stronger than round threads and are often used in high-load applications. They’re generally cheaper to manufacture and are more difficult to break. And unlike square threads, which have a 0deg thread angle, these threads can’t be broken easily with a screwdriver.
A screw’s head is made of a series of spiral-like structures that extend from a cylindrical part to a tip. This portion of the screw is called the shank and is made of the smallest area. The shank is the portion that applies more force to the object. As the shaft extends from the head, it becomes thinner and narrow, forming a pointed tip. The head is the most important part of the screw, so it needs to be strong to perform its function.
The diameter of the screw shaft is measured in millimeters. The M8 screw has a thread pitch of 1.25 mm. Generally, the size of the screw shaft is indicated by the major and minor diameter. These dimensions are appended with a multiplication sign (M8x1).
Applications
The design of screws, including their size and shape, determines their critical rotating speeds. These speeds depend on the threaded part of the screw, the helix angle, and the geometry of the contact surfaces. When applied to a screw, these limits are referred to as “permissible speed limits.” These maximum speeds are meant for short periods of time and optimized running conditions. Continuous operation at these speeds can reduce the calculated life of a nut mechanism.
The main materials used to manufacture screws and screw shafts include steel, stainless steel, titanium, bronze, and brass. Screws may be coated for corrosion resistance, or they may be made of aluminium. Some materials can be threaded, including Teflon and nylon. Screw threads can even be molded into glass or porcelain. For the most part, steel and stainless steel are the most common materials for screw shafts. Depending on the purpose, a screw will be made of a material that is suitable for the application.
In addition to being used in fasteners, screw shafts are used in micrometers, drillers, conveyor belts, and helicopter blades. There are numerous applications of screw shafts, from weighing scales to measuring lengths. If you’re in the market for a screw, make sure to check out these applications. You’ll be happy you did! They can help you get the job done faster. So, don’t delay your next project.
If you’re interested in learning about screw sizing, then it’s important to know the axial and moment loads that your screws will experience. By following the laws of mechanics and knowing the load you can calculate the nominal life of your screw. You can also consider the effect of misalignment, uneven loading, and shocks on your screw. These will all affect the life of your screw. Then, you can select the right screw.

The Four Basic Components of a Screw Shaft
There are 4 basic components of a screw shaft: the Head, the Thread angle, and the Threaded shank. These components determine the length, shape, and quality of a screw. Understanding how these components work together can make purchasing screws easier. This article will cover these important factors and more. Once you know these, you can select the right type of screw for your project. If you need help choosing the correct type of screw, contact a qualified screw dealer.
Thread angle
The angle of a thread on a screw shaft is the difference between the 2 sides of the thread. Threads that are unified have a 60 degree angle. Screws have 2 parts: a major diameter, also known as the screw’s outside diameter, and a minor diameter, or the screw’s root diameter. A screw or nut has a major diameter and a minor diameter. Each has its own angle, but they all have 1 thing in common – the angle of thread is measured perpendicularly to the screw’s axis.
The pitch of a screw depends on the helix angle of the thread. In a single-start screw, the lead is equal to the pitch, and the thread angle of a multiple-start screw is based on the number of starts. Alternatively, you can use a square-threaded screw. Its square thread minimizes the contact surface between the nut and the screw, which improves efficiency and performance. A square thread requires fewer motors to transfer the same load, making it a good choice for heavy-duty applications.
A screw thread has 4 components. First, there is the pitch. This is the distance between the top and bottom surface of a nut. This is the distance the thread travels in a full revolution of the screw. Next, there is the pitch surface, which is the imaginary cylinder formed by the average of the crest and root height of each tooth. Next, there is the pitch angle, which is the angle between the pitch surface and the gear axis.
Head
There are 3 types of head for screws: flat, round, and hexagonal. They are used in industrial applications and have a flat outer face and a conical interior. Some varieties have a tamper-resistant pin in the head. These are usually used in the fabrication of bicycle parts. Some are lightweight, and can be easily carried from 1 place to another. This article will explain what each type of head is used for, and how to choose the right 1 for your screw.
The major diameter is the largest diameter of the thread. This is the distance between the crest and the root of the thread. The minor diameter is the smaller diameter and is the distance between the major and minor diameters. The minor diameter is half the major diameter. The major diameter is the upper surface of the thread. The minor diameter corresponds to the lower extreme of the thread. The thread angle is proportional to the distance between the major and minor diameters.
Lead screws are a more affordable option. They are easier to manufacture and less expensive than ball screws. They are also more efficient in vertical applications and low-speed operations. Some types of lead screws are also self-locking, and have a high coefficient of friction. Lead screws also have fewer parts. These types of screw shafts are available in various sizes and shapes. If you’re wondering which type of head of screw shaft to buy, this article is for you.
Threaded shank
Wood screws are made up of 2 parts: the head and the shank. The shank is not threaded all the way up. It is only partially threaded and contains the drive. This makes them less likely to overheat. Heads on wood screws include Oval, Round, Hex, Modified Truss, and Flat. Some of these are considered the “top” of the screw.
Screws come in many sizes and thread pitches. An M8 screw has a 1.25-mm thread pitch. The pitch indicates the distance between 2 identical threads. A pitch of 1 is greater than the other. The other is smaller and coarse. In most cases, the pitch of a screw is indicated by the letter M followed by the diameter in millimetres. Unless otherwise stated, the pitch of a screw is greater than its diameter.
Generally, the shank diameter is smaller than the head diameter. A nut with a drilled shank is commonly used. Moreover, a cotter pin nut is similar to a castle nut. Internal threads are usually created using a special tap for very hard metals. This tap must be followed by a regular tap. Slotted machine screws are usually sold packaged with nuts. Lastly, studs are often used in automotive and machine applications.
In general, screws with a metric thread are more difficult to install and remove. Fortunately, there are many different types of screw threads, which make replacing screws a breeze. In addition to these different sizes, many of these screws have safety wire holes to keep them from falling. These are just some of the differences between threaded screw and non-threaded. There are many different types of screw threads, and choosing the right 1 will depend on your needs and your budget.
Point
There are 3 types of screw heads with points: cone, oval, and half-dog. Each point is designed for a particular application, which determines its shape and tip. For screw applications, cone, oval, and half-dog points are common. Full dog points are not common, and they are available in a limited number of sizes and lengths. According to ASTM standards, point penetration contributes as much as 15% of the total holding power of the screw, but a cone-shaped point may be more preferred in some circumstances.
There are several types of set screws, each with its own advantage. Flat-head screws reduce indentation and frequent adjustment. Dog-point screws help maintain a secure grip by securing the collar to the screw shaft. Cup-point set screws, on the other hand, provide a slip-resistant connection. The diameter of a cup-point screw is usually half of its shaft diameter. If the screw is too small, it may slack and cause the screw collar to slip.
The UNF series has a larger area for tensile stress than coarse threads and is less prone to stripping. It’s used for external threads, limited engagement, and thinner walls. When using a UNF, always use a standard tap before a specialized tap. For example, a screw with a UNF point is the same size as a type C screw but with a shorter length.
Spacer
A spacer is an insulating material that sits between 2 parts and centers the shaft of a screw or other fastener. Spacers come in different sizes and shapes. Some of them are made of Teflon, which is thin and has a low coefficient of friction. Other materials used for spacers include steel, which is durable and works well in many applications. Plastic spacers are available in various thicknesses, ranging from 4.6 to 8 mm. They’re suitable for mounting gears and other items that require less contact surface.
These devices are used for precision fastening applications and are essential fastener accessories. They create clearance gaps between the 2 joined surfaces or components and enable the screw or bolt to be torqued correctly. Here’s a quick guide to help you choose the right spacer for the job. There are many different spacers available, and you should never be without one. All you need is a little research and common sense. And once you’re satisfied with your purchase, you can make a more informed decision.
A spacer is a component that allows the components to be spaced appropriately along a screw shaft. This tool is used to keep space between 2 objects, such as the spinning wheel and an adjacent metal structure. It also helps ensure that a competition game piece doesn’t rub against an adjacent metal structure. In addition to its common use, spacers can be used in many different situations. The next time you need a spacer, remember to check that the hole in your screw is threaded.
Nut
A nut is a simple device used to secure a screw shaft. The nut is fixed on each end of the screw shaft and rotates along its length. The nut is rotated by a motor, usually a stepper motor, which uses beam coupling to accommodate misalignments in the high-speed movement of the screw. Nuts are used to secure screw shafts to machined parts, and also to mount bearings on adapter sleeves and withdrawal sleeves.
There are several types of nut for screw shafts. Some have radial anti-backlash properties, which prevent unwanted radial clearances. In addition, they are designed to compensate for thread wear. Several nut styles are available, including anti-backlash radial nuts, which have a spring that pushes down on the nut’s flexible fingers. Axial anti-backlash nuts also provide thread-locking properties.
To install a ball nut, you must first align the tangs of the ball and nut. Then, you must place the adjusting nut on the shaft and tighten it against the spacer and spring washer. Then, you need to lubricate the threads, the ball grooves, and the spring washers. Once you’ve installed the nut, you can now install the ball screw assembly.
A nut for screw shaft can be made with either a ball or a socket. These types differ from hex nuts in that they don’t need end support bearings, and are rigidly mounted at the ends. These screws can also have internal cooling mechanisms to improve rigidity. In this way, they are easier to tension than rotating screws. You can also buy hollow stationary screws for rotator nut assemblies. This type is great for applications requiring high heat and wide temperature changes, but you should be sure to follow the manufacturer’s instructions.

What Are Screw Shaft Threads?
A screw shaft is a threaded part used to fasten other components. The threads on a screw shaft are often described by their Coefficient of Friction, which describes how much friction is present between the mating surfaces. This article discusses these characteristics as well as the Material and Helix angle. You’ll have a better understanding of your screw shaft’s threads after reading this article. Here are some examples. Once you understand these details, you’ll be able to select the best screw nut for your needs.
Coefficient of friction between the mating surfaces of a nut and a screw shaft
There are 2 types of friction coefficients. Dynamic friction and static friction. The latter refers to the amount of friction a nut has to resist an opposing motion. In addition to the material strength, a higher coefficient of friction can cause stick-slip. This can lead to intermittent running behavior and loud squeaking. Stick-slip may lead to a malfunctioning plain bearing. Rough shafts can be used to improve this condition.
The 2 types of friction coefficients are related to the applied force. When applying force, the applied force must equal the nut’s pitch diameter. When the screw shaft is tightened, the force may be removed. In the case of a loosening clamp, the applied force is smaller than the bolt’s pitch diameter. Therefore, the higher the property class of the bolt, the lower the coefficient of friction.
In most cases, the screwface coefficient of friction is lower than the nut face. This is because of zinc plating on the joint surface. Moreover, power screws are commonly used in the aerospace industry. Whether or not they are power screws, they are typically made of carbon steel, alloy steel, or stainless steel. They are often used in conjunction with bronze or plastic nuts, which are preferred in higher-duty applications. These screws often require no holding brakes and are extremely easy to use in many applications.
The coefficient of friction between the mating surfaces of t-screws is highly dependent on the material of the screw and the nut. For example, screws with internal lubricated plastic nuts use bearing-grade bronze nuts. These nuts are usually used on carbon steel screws, but can be used with stainless steel screws. In addition to this, they are easy to clean.
Helix angle
In most applications, the helix angle of a screw shaft is an important factor for torque calculation. There are 2 types of helix angle: right and left hand. The right hand screw is usually smaller than the left hand one. The left hand screw is larger than the right hand screw. However, there are some exceptions to the rule. A left hand screw may have a greater helix angle than a right hand screw.
A screw’s helix angle is the angle formed by the helix and the axial line. Although the helix angle is not usually changed, it can have a significant effect on the processing of the screw and the amount of material conveyed. These changes are more common in 2 stage and special mixing screws, and metering screws. These measurements are crucial for determining the helix angle. In most cases, the lead angle is the correct angle when the screw shaft has the right helix angle.
High helix screws have large leads, sometimes up to 6 times the screw diameter. These screws reduce the screw diameter, mass, and inertia, allowing for higher speed and precision. High helix screws are also low-rotation, so they minimize vibrations and audible noises. But the right helix angle is important in any application. You must carefully choose the right type of screw for the job at hand.
If you choose a screw gear that has a helix angle other than parallel, you should select a thrust bearing with a correspondingly large center distance. In the case of a screw gear, a 45-degree helix angle is most common. A helix angle greater than zero degrees is also acceptable. Mixing up helix angles is beneficial because it allows for a variety of center distances and unique applications.
Thread angle
The thread angle of a screw shaft is measured from the base of the head of the screw to the top of the screw’s thread. In America, the standard screw thread angle is 60 degrees. The standard thread angle was not widely adopted until the early twentieth century. A committee was established by the Franklin Institute in 1864 to study screw threads. The committee recommended the Sellers thread, which was modified into the United States Standard Thread. The standardized thread was adopted by the United States Navy in 1868 and was recommended for construction by the Master Car Builders’ Association in 1871.
Generally speaking, the major diameter of a screw’s threads is the outside diameter. The major diameter of a nut is not directly measured, but can be determined with go/no-go gauges. It is necessary to understand the major and minor diameters in relation to each other in order to determine a screw’s thread angle. Once this is known, the next step is to determine how much of a pitch is necessary to ensure a screw’s proper function.
Helix angle and thread angle are 2 different types of angles that affect screw efficiency. For a lead screw, the helix angle is the angle between the helix of the thread and the line perpendicular to the axis of rotation. A lead screw has a greater helix angle than a helical one, but has higher frictional losses. A high-quality lead screw requires a higher torque to rotate. Thread angle and lead angle are complementary angles, but each screw has its own specific advantages.
Screw pitch and TPI have little to do with tolerances, craftsmanship, quality, or cost, but rather the size of a screw’s thread relative to its diameter. Compared to a standard screw, the fine and coarse threads are easier to tighten. The coarser thread is deeper, which results in lower torques. If a screw fails because of torsional shear, it is likely to be a result of a small minor diameter.
Material
Screws have a variety of different sizes, shapes, and materials. They are typically machined on CNC machines and lathes. Each type is used for different purposes. The size and material of a screw shaft are influenced by how it will be used. The following sections give an overview of the main types of screw shafts. Each 1 is designed to perform a specific function. If you have questions about a specific type, contact your local machine shop.
Lead screws are cheaper than ball screws and are used in light-duty, intermittent applications. Lead screws, however, have poor efficiency and are not recommended for continuous power transmission. But, they are effective in vertical applications and are more compact. Lead screws are typically used as a kinematic pair with a ball screw. Some types of lead screws also have self-locking properties. Because they have a low coefficient of friction, they have a compact design and very few parts.
Screws are made of a variety of metals and alloys. Steel is an economical and durable material, but there are also alloy steel and stainless steel types. Bronze nuts are the most common and are often used in higher-duty applications. Plastic nuts provide low-friction, which helps reduce the drive torques. Stainless steel screws are also used in high-performance applications, and may be made of titanium. The materials used to create screw shafts vary, but they all have their specific functions.
Screws are used in a wide range of applications, from industrial and consumer products to transportation equipment. They are used in many different industries, and the materials they’re made of can determine their life. The life of a screw depends on the load that it bears, the design of its internal structure, lubrication, and machining processes. When choosing screw assemblies, look for a screw made from the highest quality steels possible. Usually, the materials are very clean, so they’re a great choice for a screw. However, the presence of imperfections may cause a normal fatigue failure.
Self-locking features
Screws are known to be self-locking by nature. The mechanism for this feature is based on several factors, such as the pitch angle of the threads, material pairing, lubrication, and heating. This feature is only possible if the shaft is subjected to conditions that are not likely to cause the threads to loosen on their own. The self-locking ability of a screw depends on several factors, including the pitch angle of the thread flank and the coefficient of sliding friction between the 2 materials.
One of the most common uses of screws is in a screw top container lid, corkscrew, threaded pipe joint, vise, C-clamp, and screw jack. Other applications of screw shafts include transferring power, but these are often intermittent and low-power operations. Screws are also used to move material in Archimedes’ screw, auger earth drill, screw conveyor, and micrometer.
A common self-locking feature for a screw is the presence of a lead screw. A screw with a low PV value is safe to operate, but a screw with high PV will need a lower rotation speed. Another example is a self-locking screw that does not require lubrication. The PV value is also dependent on the material of the screw’s construction, as well as its lubrication conditions. Finally, a screw’s end fixity – the way the screw is supported – affects the performance and efficiency of a screw.
Lead screws are less expensive and easier to manufacture. They are a good choice for light-weight and intermittent applications. These screws also have self-locking capabilities. They can be self-tightened and require less torque for driving than other types. The advantage of lead screws is their small size and minimal number of parts. They are highly efficient in vertical and intermittent applications. They are not as accurate as lead screws and often have backlash, which is caused by insufficient threads.
