Fastener standards are instrumental in specifying, testing, and evaluating the material, dimensional, mechanical, and metallurgical properties of the various forms of hardware fasteners. These fasteners are used to mechanically join or affix other hardware objects together, and come in many forms which include rivets, nuts, bolts, studs, screws, washers, eyebolts, nails, and threaded fasteners. These fastener standards allow hardware product manufacturers, as well as the end-users of such products, to examine and assess fasteners to ensure their strength and quality towards safe utilization.
