A socket cap screw, also known as a socket head cap screw, socket screw, or Allen bolt, is a type of cap

screw with a cylindrical head and hexagonal drive hole.

Socket head cap screws are used for applications with limited space. They have cylindrical head and

internal wrenching features hexagon socket that allow them to be used in locations where externally

wrenched fasteners are not suitable.

A socket cap screw is most commonly driven with an allen wrench or hex key
