A hex screw is a type of fastener characterized by a hexagonal head, which allows for easy tightening and loosening using a wrench or socket. These screws are commonly made from materials like steel or stainless steel, providing strength and durability for various applications. They are often used in construction, machinery, and automotive industries. The design of a hex screw includes a threaded shaft that can be inserted into a pre-drilled hole, securing two or more objects together. Hex screws come in various sizes and lengths, making them versatile for different projects. They are often paired with nuts to create a secure fastening system.
