Allen/ Hexagonal Socket, Cap Head, Screw/ Bolt

Allen/ Hexagonal, Socket Cap Screw/ Bolts come as 'sets' and 'bolts'. The, ‘SET’, term is used to describe a fastener that is fully threaded in lengths up to and around 1 inch (from the underside of the head), depending on the diameter. As the diameter increases the set length will increase. Over around 1 inch (depending on the diameter) in length the fastener will have a, 'shoulder,' or unthreaded area (plain shank) under the head. This space of unthreaded area confirms that the fastener is now a bolt (cap head, bolt in this case). Some people might simply call them Allen or, 'Allan bolts,' in association with the Allen, Hexagonal Key which is used to tighten and loosen the fastener. So, ‘Socket,’ refers to the hexagon shaped indentation found on the top of the fasteners’ 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.
