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.
Structural Bolts Diameters
Structural Bolts are available on the FCH Network with Imperial/US diameters that range from #1 to 2 1/4 and with Metric diameters that range from M12 to M42. The length of Structural Bolts is usually measured from the point to the underside of the head.
Structural Bolts are available on the FCH Network in materials that range from Steel to Copper
Structural Bolts Finishes
Structural Bolts are available on the FCH Network in finishes or coatings that range from Plain to Phosphate
