    Socket Cap Head Fasteners come as 'sets' and 'bolts'. The, ‘SET’, term is used to describe a fastener that is fully threaded in lengths up to and around 1 inch (from the underside of the head. Over 1 inch in length the fastener will have a, 'shoulder,' or unthreaded area under the head. This space of unthreaded area confirms that the fastener is now a bolt (cap head, bolt in this case). Some people might simply call them Allen or, 'Allan bolts,' in association with the Allen, Hexagonal Key which is used to tighten and loosen the fastener. So, ‘Socket,’ refers to the hexagon shaped indentation found on the top of the fasteners’ head.

      Metric Coarse and Metric Fine threads 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. Coarse threads are the, 'normal', most common versions.
