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.
Metric Coarse and Metric Fine (M1, M2, M3.... M10, etc.) thread/ dimensions are measured in Millimetres (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 and a fine one has more. Coarse is used for heavier loads and fine is used for lighter loads prone to vibrations.
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)
