Button Socket Description
A socket screw with a button head is usually applied to fasten components where aesthetics (looks) are more important. The domed shaped or 'half spherical' shape of the head softens it's appearance and touch.

METRIC THREAD
Metric Coarse and Metric Fine
Are 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 and a fine one has more. Coarse is used for heavier loads and fine is used for lighter loads prone to vibrations.
