What is a cap screw?

A cap screw, also known as a socket screw, is a type of fastener that is designed to be used with a matching internal-wrenching socket, or Allen wrench. Cap screws have a cylindrical head and come in a variety of sizes, lengths, and types of materials, such as stainless steel, alloy steel, and carbon steel.

Cap screws are commonly used in applications where a strong, durable fastening solution is required, such as in machinery, automotive, and construction industries. They are often used to secure two or more components together and can provide a high level of tensile strength and resistance to vibration.

Cap screws are available in different styles, such as socket head cap screws, button head cap screws, and flat head cap screws. They can be easily installed and removed using an Allen wrench or hex key, making them a convenient and versatile choice for many applications.

Overall, cap screws are a reliable and effective fastening solution that offer high strength and durability for a wide range of industrial and mechanical applications.
