1/2-13 X 20 HEX BOLT A307 GRADE A

A hex bolt, also known as a hexagonal bolt or a hex head bolt, is a type of threaded fastener commonly used to join two or more components together. It consists of a cylindrical shaft with external threads and a six-sided head, which is designed to be turned using a wrench or socket to tighten or loosen the bolt. The threaded portion of the bolt allows it to be securely fastened into a corresponding threaded hole or nut.

Hex bolts are widely used in various applications, including construction, manufacturing, automotive, machinery and more. They come in various sizes, materials and grades, each tailored to specific requirements based on factors such as load-bearing capacity, corrosion resistance and environmental conditions.
