Socket Head Cap Screw ASME B18.3

A socket head cap screw has a cylindrical head with a recessed hex drive. The deep socket allows the hex key to seat fully, and the head fits into a counterbored hole to leave a flush surface. It is installed by turning the hex key until the head seats in the counterbore. Commonly used in machines, tooling, jigs and moulds where access is limited.
