Socket Head Cap Screws

A socket head cap screw is a type of machine screw that features a cylindrical head with a recess or socket designed to accept a matching driver tool, such as an Allen wrench or a hex key.

Socket head cap screws are characterized by the following features:

1. Head design: The head of the screw is cylindrical in shape and has a hexagonal or other shaped recess or socket in the top, allowing it to be driven by a corresponding hex key or Allen wrench.
2. Head style: The head can be designed in different styles, such as flat head (where the top surface is flat), button head (with a rounded top), or socket head (with a cylindrical head).
3. Thread: Socket head cap screws have a partially or fully threaded shank, typically with a unified or metric thread pattern.
4. Material: They can be made from various materials, including steel, stainless steel, aluminum, or other alloys, depending on the intended application and required strength.

Socket head cap screws are widely used in many industries, including automotive, machinery, construction, and furniture assembly, due to their high strength, low profile, and the ability to be tightened or loosened using a hex key or Allen wrench. They are often preferred over slotted or Phillips head screws when a secure, tamper-resistant fastening is required or when the screw head needs to sit flush with the surface.
