Material: High Tensile (12.9 Grade) - Plain/ Self Colour.

Grade 12.9 steel has a higher carbon content and is therefore stiffer and harder than your regular 8.8 high tensile steel. Self-colour fasteners tend to be oiled or greased to prolong their performance

 

Allen/ Hexagonal Socket, Cap Head, Screw/ Bolt

Allen/ Hexagonal, Socket Cap Screw/ Bolts 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), depending on the diameter. As the diameter increases the set length will increase. Over around 1 inch (depending on the diameter) in length the fastener will have a, 'shoulder,' or unthreaded area (plain shank) 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 Threads.

Metric Coarse and Metric Fine threads are in millimetre (mm) units and referes to the distance between the helical coils. The Metric measurement system was 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. Standard (most commonly used) Coarse Threads are used for heavier loads e.g. Fabricating the Eiffel Tower and Fine Threads are used for lighter loads prone to vibrations e.g. motor and machine applications. Coarse threads are the, 'normal', most common versions.
