A Brass bolt is a form of threaded fastener with an external male thread made from Brass. Bolts are generally used as connectors with applications in various mechanical and electrical industries.

Bolts use a wide variety of head designs, as do screws. These are designed to engage with the tool used to tighten them. Some bolt heads instead lock the bolt in place, so that it does not move and a tool is only needed for the nut end.

Earlier bolt had square heads, made by forging. Although much more common today is the hexagonal head. These are fixed in place and twisted tightly by a spanner or wrench, of which there are many forms.

Head designs that overlap both are the Allen and Torx heads; hexagonal or splined sockets. These modern designs span a large range of sizes and can carry a considerable torque.
