A socket head is a type of screw or bolt that has a cylindrical head with a hexagonal recess, also known as a hex socket or Allen socket, on the top.
This type of head is designed to be tightened or loosened using a tool called a socket wrench, which has a matching hexagonal shape that fits into the recess in the head of the screw or bolt.
Socket head screws and bolts are commonly used in applications where the screw or bolt needs to be tightened to a specific torque, or rotational force, such as in automotive and aerospace manufacturing.
The socket head design allows for precise tightening and prevents the screw or bolt from being turned using a standard screwdriver, which can help to prevent tampering or accidental loosening.
