Manufacturing of Bolt

The bolt consists of a head and a cylindrical body with screw threads along a portion of its length. The nut is the female member of the pair, having internal threads to match those of the bolt . A bolt is a form of threaded fastener with an external male thread requiring a matching pre-formed female thread such as a nut.

Bolts are tools used to fasten and secure the faces of assemblies. They are threaded and come with a matching nut. Their purpose is to connect aligned unthreaded holes by being placed through the aligned holes and secured with the bolt's nut.
