A hex bolt, also known as a hexagonal head bolt, is a type of fastener with a hexagonal-shaped head and a threaded shaft. It is designed to be tightened or loosened using a hexagonal wrench or socket. Hex bolts are commonly used in construction, automotive, and machinery applications. They are available in a variety of materials, including steel, stainless steel, and brass, and in a range of sizes and grades to meet different strength and corrosion resistance requirements. Hex bolts can be used in conjunction with a variety of other fasteners, such as nuts, washers, and lock washers, to secure joints and prevent them from coming loose.
