Bolt

A bolt is a type of fastener typically made of metal, characterized by a cylindrical body with a threaded shaft and a head. Bolts are designed to be inserted through holes in assembled parts and are secured with a nut on the opposite end or by tightening into a tapped hole. The primary purpose of a bolt is to hold objects together securely. Bolts come in various sizes and thread types, making them versatile for different applications in construction, manufacturing, and machinery. They are essential components in many mechanical assemblies, providing strength and stability to structures and equipment.
