Bolt

Bolt is the term used for a partially threaded fastener, with a head designed to be used with a nut and washer. 

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)

METRIC THREADS

Metric Coarse and Metric Fine (M1, M2, M3.... M10, etc.) 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.
