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. 1/2-13 X 1 3/4 ASTM A193 B7 HEAVY HEX BOLT PLAIN
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. 1/2-13 X 1 3/4 A193 B7 ZINC PLATED HEAVY HEX BOLT
