What is a socket cap screw/ bolt?
The, ‘Socket Cap Screw/ Allen Bolt,’ term is used to describe a enerthat 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 ener 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 eners’ head. Here, you can use a hexagon key (Allen Key) to tighten and loosen the ener. 'Cap' refers to the cylindrical shaped head.
