A490 Heavy Hex Structural Bolts

A490 Heavy Hex Bolts are designed for use in critical structural steel connections that require greater yield and tensile strength than what A325 Heavy Hex Bolts can provide.  The heavy hex head and washer face provides a substantial bearing surface for added strength in heavy critical joints, while the shorter thread length provides ample shank for steel-to-steel connections.  Type 1 A490 Heavy Hex Bolts are manufactured from alloy steel, and quenched & tempered to achieve the desired hardness.  Type 3 A490 Heavy Hex Bolts are manufactured from weathering steel, and while the strength properties mimic those of Type 1, the addition of copper, chromium and nickel provides exceptional corrosion protection, making this the preferred material for use in extreme element conditions.
