Product details

Hex head bolts are a type of fastener that have a hexagonal-shaped head and a threaded shaft. They are used to join two or more pieces of metal, wood, plastic, or other materials together. Hex head bolts are commonly used in construction, automotive, and industrial applications. They can be tightened or loosened with a wrench or a socket that fits the size of the head. Hex head bolts come in various sizes, lengths, grades, and materials. The size of the bolt is determined by the diameter and pitch of the threads. The length of the bolt is measured from the underside of the head to the end of the shaft.
