Extreme-Strength Steel Extra-Wide Hex
Nuts for Structural Applications—Grade DH
These nuts are designed to secure ASTM A325 bolts in structural joints. Also known as heavy hex nuts, they are about 10% wider and taller than standard hex nuts.
Hot-dipped galvanized steel nuts have a thick coating for good corrosion resistance. They must be used with other hot-dipped galvanized fasteners.

High-Strength Steel Extra-Wide Hex Nuts
for Structural Applications—Grade C
These nuts are designed to secure ASTM A325 bolts in structural joints. Also known as heavy hex nuts, they are about 10% wider and taller than standard hex nuts and distribute the load over a large area.
Hot-dipped galvanized steel nuts have a thick coating for good corrosion resistance. They must be used with other hot-dipped galvanized fasteners.
