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.
Hex bolts (six sided heads) are the industry standard for fasteners with forged heads.
Steel Grades: 4.6, 8.8, 10.9, 12.9
