2H Heavy Hex Nut, Mechanical Galvanized

ASTM A194 Grade 2H heavy hex nuts are high-strength, heat-treated nuts designed for demanding applications, including flange bolting, structural connections, and use with high-strength bolts. These carbon and alloy steel nuts are ideal for high-pressure and high-temperature environments and are commonly paired with bolts like ASTM A193 Grade B7, F3125 Grade A325, and F1554 Grade 105. Featuring a larger bearing surface than standard hex nuts, they offer enhanced load distribution and durability. Each nut is marked with the "2H" grade symbol and the manufacturer's ID for traceability. Finished with a mechanically galvanized coating, they offer reliable corrosion resistance and meet dimensional standards set by ASME B18.2.2.
