Hex Bolts - BSF - Self Colour

A hexagon bolt, or hex bolt to give it its more common name, is a threaded bolt with a plain shank and hexagon shaped 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 It was superseded by the UNF thread type in the 1940’s.

Steel products described as having a self colour finish are best suited to internal applications, as they have no additional protection against corrosion. The shade of a self colour finish can vary from bright metal to black, and it will change over time with oxidisation.

If you plan to use self colour finishes outdoors you should paint them to give them a protective coating.
