High-Strength Steel Extra-Wide Hex Nuts
Also known as heavy hex nuts, these nuts are about 10% wider and taller than standard hex nuts and distribute the load over a large area. They're about 25% stronger than medium-strength steel extra-wide hex nuts and comparable in strength to Class 10.9 bolts.
Zinc-plated steel nuts resist corrosion in wet environments.
Hot-dipped galvanized steel nuts have a thick coating for better corrosion resistance than zinc-plated steel nuts. They must be used with other hot-dipped galvanized fasteners.
