Hex Bolts

Hex bolts are used to fasten two or more parts together to form an assembly either because it cannot be manufactured as a single part or to allow for maintenance and repair disassembly. By definition “A Bolt is a headed and externally threaded mechanical device designed for insertion through holes in assembled parts to mate with a nut and is normally intended to be tightened or released by turning that nut.” When used with a preformed internally threaded (tapped) hole, the hex bolt’s head is turned to tighten, which technically makes it a screw. Hex bolts are also known as: finished hex bolts, hex head bolts, cap screws, hex cap screws, hex head cap screws and, if fully threaded, tap bolts, hex tap bolts and hex head tap bolts.
