Set screws are normally stainless steel and brass material, but carbon steel and titanium, aluminum materials are also available for you.

You Need To Know When You Purchase Screws


For standard set screws, normally you need to know the thread size, screw head size. Length, etc, or Custom set screw, Then you need to have a drawing

Head Type, Drive Type, Thread Type

You need to know what kind of types customer needs? Phillip, Torx, Slotted or others, and Pan, truss, Countersunk, Round, etc, For thread, is full machine thread or half machine thread, or Self-tapping, etc


Some customer does not have high requirements, specification can be the same no matter carbon steel or stainless steel. but for titanium or copper that means the customer has special requirements. also different material, the cost will be much different.


The finish is very important for screws and bolts. if the material is stainless steel, aluminum, copper, brass, then the finish normally will be natural, but for carbon steel, could be a black oxide, plating, dacromet etc


Some materials are not hard features, such as carbon steel. Generally, the material grade of carbon steel without hardening is basically below grade 4.8, but in order to match the performance, customers will require it to reach grades 6.8, 8.8, 10.8, or even 12.9. Generally, this requires hardening

Salt spray test

Some customer does not have a high salt spray test. As we all know, carbon steel has no anti-corrosion ability. Even if it is surface treated, its anti-corrosion ability needs to be judged, and the method of this judgment is usually determined by a salt spray test.


The screw is just an accessory. As a screw manufacturer, we only know about the screw, but the customer does not know the supporting products. Therefore, when necessary, we need to inform the customer of the use of the screw and understand the use of the screw. Only then can we determine whether the screw the customer wants is in line with his product

Set screws can be identified with their signature headless body. The entire body of the fastener is threaded and it comes in various dimensions. To ensure fasten the set screw in place, a special internal wrenching drive or an Allen key is used. Once the components or objects are fastened, the set screw exerts a clamping force in order to ensure the components are in place. in which case it may be called a grub screw or blind screw.

Set Screws Application.

Set screws are used in one component that has to be fixed within another one without any protrusions which could decrease the efficiency of the equipment. For example, fastening a gear and shaft assembly with a regular hex bolt might be inefficient as the hex head might cause inconveniences to the smooth operation of the assembly. In such situations, where protrusions are not desired, a set screw can effectively fasten the components together without interfering with the operations.

Types Of Set Screws

Set screws have different point types based on the characteristics required of them, A few examples of point types are flat point, domed point, cone point, cup point, extended point, and knurled cup point.

  • Dog Point Set Screws: Dog point or Extended point set screws to have a tubular tip to mate with a corresponding hole in the workpiece, allowing the shaft to rotate without dislodging the parts
  • Cup Point Set Screws: The most commonly used set screw, the cup-shaped edge cuts into the surface material to prevent the part from loosening
  • Knurled cup point screws: The knurls dig into the surface to provide strong holding power in high vibration applications.
  • Half Dog Point Set screws: Half dog points perform the same as full dogs, the point is half as long
  • Cone Point Set Screws: The Sharp cone point penetrates the surface, offering superior holding power for permanent setting.
  • Flat Point Set Screws: The flat point does not damage or deform the materials they are set into ideal for applications where you may need to make adjustments
  • Nylon Point Set Screws: Nylon tip set screws to have a dog point tip that is made of nylon and will not damage the mating parts or surface
  • Oval Point Set Screws: An oval point set screw has a convex oval point on one end, they are used in applications where repeated adjustments need to be made without significantly damaging the mating material or part

Set screws drive types

Set screws also have a variety of drive types. like straight slot, Hex Socket, Square socket, External hex, External square, Bristol spline.

  • STRAIGHT SLOT: straight slotted set screws use a flat screw driver to fix and remove, Extremely little torque is required to maintain this in place yet it mostly finds its use in very simple applications.
  • HEX SOCKET: Hexagon Socket Set Screws are threaded fasteners without a head that have a hexagon socket drive recessed into the body of the screw. Hexagon Socket Set Screws are used to bind two objects together by threading into one object and exerting pressure on the other object.
  • SQUARE SOCKET: Square socket set screws also called Robertson or scrulox, come with a square protrusion on the tool. Both the tool and socket have a slight taper which makes the installation of the fastener very easy.
  • EXTERNAL HEX: With the exterior hex screw drive, a 6-sided device or a unique wrench with a combination or flexible point socket needs to be utilized. This head kind is liked over the square socket in a position that has a limiting area bordering the set screw.
  • EXTERNAL SQUARE: This requires a 4-sided adjustable wrench or an open-ended wrench to be made use of on it for any operation.
  • BRISTOL SPLINE: This set screw features four or 6 splines at the head. Nevertheless, this does not make the bolts tamper-resistant. The grooves are cut using a square-cornered broach, giving the outer edges of the drivers a slight undercut. As soon as the torque is used in the appropriate instructions, the possibility of splitting the fastener is completely eliminated.

Common sizes range from #0 to #12 and 1/4″ to 1 1/2″—small sizes are expressed as whole numbers and large sizes as fractional inches—and lengths span from 1/16″ to 6″ for socket set screws. For square head set screws, available sizes are from #8 to #12 and 1/4″ to 1 1/2″, while lengths range from 7/32″ to 12″
