The, ‘Socket Screw/ Allen Bolt,’ term is used to describe a fastener that is partially threaded in lengths over 1 inch; generally speaking (they can vary up to 12mm with different diameters). The space of unthreaded area confirms that the fastener is a bolt. Some engineers may call them screws if the person only uses the shorter length range of sizes, under an inch. ‘Socket,’ refers to the hexagon shaped indentation found on the top of the fasteners’ head. Here, you can use a hexagon key (Allen Key) to tighten and loosen the fastener.

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.
