What is a socket cap screw/ bolt?

The, ‘Socket Cap Screw/ Allen Bolt,’ term is used to describe a fastener that is either fully or partially threaded. A screw is fully threaded and a bolt is partialy threaded. Some engineers may call them screws if the person uses the shorter length range of sizes. The thread stays the same length as the fastener gets longer and the maximum length of thread is equal to 2.5 times the diameter (or thereabouts). ‘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. 'Cap' refers to the cylindrical shaped head.

Allen socket, cap head screw/ bolt 12.9 Grade, High Tensile Applications

An allen socket, cap head screw is best used in engineering applications where you are joining components under heat and or high compression, tension, torque or shearing stress. Such as, fastening together automotive or machinery parts. Allen socket, cap head screw/ bolts are designed to be used as a temporary fastener where components need maintenance or should be replaced due to functional wear.

What is Metric Coarse and What is Metric Fine?

Different threads have different applications. Metric System threads are measured in millimetre (mm) units and were developed to simplify the imperial (Inch) systems. Europe moved to this system but the Americans choose Imperial as their default because of the greater range in sizes. A coarse thread has less helical coils per mm and a fine one has more. Coarse is used for heavier loads/ stress and fine is used for loads prone to vibrations such as in car engines. Coarse threads are the, 'normal', most common versions used as standard.
