What Are Hexagon Socket Head Bolts?

A hexagon socket head bolt, also known as a socket head cap screw, is a type of fastener with a cylindrical head and a hexagonal recess in the head. It is designed to be tightened or loosened using an Allen wrench (hex key) rather than a traditional external wrench or socket.
