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)
Zinc/ BZP Coating
Zinc coats the fastener to add moisture resistance to the steel to slow down the oxidisation (rusting) of the metal. It does not make the steel waterproof. Zinc is used for inernal application for an aesthetic shine (chrome type finish) or where there is likely to be moisture on the screw e.g. garage. Self-colour (no coating) is ok to use with a light covering of oil/ grease, when the fastener is not on show or its appearance is not important.
