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.
