What is a Cap Screw?

A cap screw, also known as a machine screw, is a threaded fastener that is used to join two or more parts together. It has a cylindrical or hexagonal-shaped head and a threaded shaft that extends from the head. The head of the cap screw is designed to be tightened with a wrench, creating a secure hold.

Types of Cap Screws

Hex Cap Screws

Hex cap screws, also known as hex bolts, have a hexagonal head that can be tightened with a wrench or pliers. They are commonly used in construction and automotive applications.

Socket Cap Screws

Socket cap screws have a cylindrical head with a socket at the top. They are tightened with an allen wrench and are commonly used in machinery and electronics.

Shoulder Bolts

Shoulder bolts have a cylindrical shoulder between the head and the threaded shaft. They are commonly used in pulleys and gears, where the shoulder acts as a bearing surface.

Uses of Cap Screws

Cap screws are used in different applications, including:

Construction

Cap screws are commonly used in construction to hold different parts together, such as beams, joists, and frames.

Machinery

Cap screws are used in machinery to hold different parts together, such as gears, pulleys, and motors.

Automotive

Cap screws are used in the automotive industry to hold different parts together, such as engines, transmissions, and suspension systems.

Conclusion

In conclusion, cap screws are a crucial fastener in construction, machinery, and automotive industries. Understanding what a cap screw is, its types, and its uses can help you choose the right fastener for your project. Whether you need a hex cap screw, socket cap screw, or shoulder bolt, make sure you choose the right one for your application.
