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.

Thread Type
British Standard Fine (BSF)
BSF was developed by R. E. B. Crompton, and his assistant George Field. BSF threads use the 55 degree Whitworth thread form. It was introduced by the British Engineering Standards Association in 1908.
British Standard Fine (BSF) is an imperial screw thread form and has a finer-pitch to it’s alternative to British Standard Whitworth (BSW) thread. They are most commonly used to fasten components found in British machinery, including cars. The British Standard threads were used before Unified, the American version of imperial threads.
Today, fasteners with a BSF thread are particularly hard to find as they are no longer mass produced.
