Hex Set Screws - BSF

Hexagon set screws, or hex sets to give them their common name, are available in both metric and imperial thread sizes in a wide range of finishes. A set screw differs from a bolt in that the shank is threaded all the way from the tip to the head.

BSF (British Standard Fine) is an imperial thread Introduced as a fine-pitch alternative to BSW and commonly used in engineering and automotive applications in the UK. It was superseded by the UNF thread type in the 1940’s.
