What is a socket cap screw/ bolt?
The, Socket Cap Screw/ Allen Bolt, term is used to describe a fastenerthat is either fully or partially threaded. A screw is fully threaded and a bolt is partialy threaded. Some engineers may call them screws if the person uses the shorter length range of sizes. The thread stays the same length as the fastener gets longer and the maximum length of thread is equal to 2.5 times the diameter (or thereabouts). Socket, refers to the hexagon shaped indentation found on the top of the fasteners head. Here, you can use a hexagon key (Allen Key) to tighten and loosen the fastener. ‘Cap’ refers to the cylindrical shaped head.
