A325 Heavy Hex Bolts
A325 Heavy Hex Bolts are designed for use in heavy industrial construction, specifically the connecting of structural steel joints. The heavy hex head and washer face provides a substantial bearing surface for added strength in critical joints, while the shorter thread length provides ample shank for steel-to-steel connections.

Types of A325 Heavy Hex Bolts
Type 1 A325 Heavy Hex Bolts are manufactured from medium carbon or medium carbon-alloy steel, and quenched & tempered to achieve the desired hardness. Type 3 A325 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.
