Hex bolts fall under The American Society of Mechanical Engineers’ (ASME) standard category “Bolts, Studs and Threaded Rod”.
These bolts are fully threaded or partially threaded depending on the length with a six sided, hexagonal head.
The ASME standard covers hex bolt dimensional specifications designated by ASME B18.2.1.
The chemical and mechanical specifications included in ASME B18.2.1 are governed by The Society of Automotive Engineers (SAE) and American Society for Testing and Materials (ASTM).
A hex screw drive uses six-sided fastener heads, and the fastener is known as a hex head cap screw. It can be turned with an adjustable wrench, combination wrench and 6- or 12-point sockets.
The hex drive is better than square drive for locations where surrounding obstacles limit wrenching access, because smaller wrench-swing arcs can still successfully rotate the fastener.
Metric sizes of the hex are specified by ISO 4032 and ISO 4033, plus ISO 4035 for Jam Nuts, and ISO 4014 and ISO 4017 for hex cap screws, ISO 4018 for Hex head screws (grade c).
