Bolt
Bolt is the term used for a partially threaded fastener (shoulder bolt/ plain shank bolt), with a head; designed to be used with a nut and washer. The shoulder appears after around 1-2 inches, depending on the diameter.
Metric Coarse (Standard Thread) dimensions are measured in Millimetre (mm) units and were developed to simplify the imperial systems. Europe moved to this system but the Americans choose Imperial as their default. A coarse thread has less helical coils per mm than a Metric Fine Thead. Coarse is used for heavier loads and fine is used for lighter loads prone to vibrations.
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 joins several 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.
