Heavy Hex Structural bolts are designed for high-strength steel to steel structural connections. Dimensionally, hex structural bolts are covered by the ASME B18.2.6 standard, and the material specifications are now covered by ASTM F3125 which replaced ASTM A325 and A490. In metric use, structural bolts are covered by DIN 6914, DIN EN 14399-4, ISO 7412 and material Classes 8.8 and 10.9.
