Heavy Hex Bolts are designed for use in a variety of high temperature, high strength industrial applications, such as with steel fabrication and general construction. 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. Heavy hex bolts can be made with a few different materials including low and medium carbon steel, alloy, and stainless steel, and are available plain, hot dipped galvanized, phosphate, zinc or cadmium plated. Some sizes of heavy hex bolts are fully threaded while other sizes offer a smooth shoulder area.

Heavy Hex Bolt Specifications

General heavy hex bolts include ASTM A307 specifications, which covers carbon steel bolts and studs ranging from 1/4” through 4” in diameter. This is the most common heavy hex bolt and includes Grades A, B, and C which denote tensile strength, configuration, and its intended use.

The ASTM A193 specification covers alloy steel and stainless steel bolt materials for high temperature and high pressure applications.

Heavy hex structural bolts are designed for steel-to-steel connections and include ASTM A325 and A490 specifications, which covers bolts from 1/2” up to 1-1/2” in diameter. Since these heavy hex bolts are intended for structural connections, they have shorter thread lengths than standard hex bolts.
