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. Orders placed before 2pm are dispatched same day (Mon-Fri).

It was used for steel bolts and nuts on much British machinery, including cars, prior to adoption of Unified, and later Metric, standards.For highly stressed conditions, especially in motorcycles, a finer thread, British Standard Cycle (BSC), was used as well. BSF was developed by R. 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. Socket Capscrews, Inch ANSI/BS 1936.
