Heavy Hex Bolts are designed for use in a variety of high-temperature, high strength industrial applications, They are used for bridges, highways, buildings, and other construction projects. Heavy hex bolts work well with construction materials such as wood and steel. They feature a thicker head than standard or regular hex bolts and offer a greater bearing surface that distributes the clamping load over a wider area. The main difference between a heavy hex bolt and a regular (or finished) hex bolt is the distance across opposite flats of the hex. Heavy hex bolts are 1/8 of an inch larger than a finished hex bolt of the same diameter. The formula for determining hex size is one-and-a-half times the diameter plus 1/8″.

Heavy Hex Nuts are oversized hex nuts for structural bolting applications. Heavy hex nuts are often called hexagon heavy nuts or large hex nuts. Heavy hexagon nuts are used with Heavy Structural Hex Bolt or screws. Heavy hex nuts are oversized, both in thickness and hexagon across flat dimensions. ASTM A194 Grade 2H heavy hex nuts are intended for use in flange bolting applications, as well as structural applications and with other high strength bolting. ASTM A194 Grade 2H covers carbon steel, alloy steel, and stainless steel nuts for bolts in high pressure or high temperature service.

 A hex nut has a smaller width across the flats and corners compared to a heavy hex nut. Heavy hex nuts are thicker and heavier in weight. The proof load strength is higher than a standard hex nut. Heavy hex nuts provide increased bearing surface area over finished nuts.
