Bolt Thread

The thread length of a shoulder bolt/ plain shank bolt tends to be 2.5 times the diameter of the fastener. Please ask for exact measurements if the shoulder is crucial.

Bolt vs Screw

A screw screws into something, a bolt joinsseveral things together from both sides of materials joined. A screw is fully threaded from underneath the head and a bolt is partially threaded (has a part-plain shank)

Self Colour – Blackedised

Fasteners in the plain uncoated finish are called Black or Self Colour finish. Fastenerwith this surface finish have no additional coating. They are blackedised and oil quenched giving thema black, oily finishthat gives a minimal amount of protection (enough for storage).

Self-colour is ok to use with a light covering of oil/ grease, when the fastener is not on show or its appearance is not important.
