Extreme-Strength Steel Extra-Wide Hex Nuts—Grade 2H
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. Grade 2H nuts are comparable in strength to Grade 9 bolts. They're about 20% stronger than high-strength steel nuts and are used in heavy machinery, such as earth-moving equipment.
Zinc yellow-chromate 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.
Black-oxide steel nuts have a dark surface color and are mildly corrosion resistant in dry environments.
Blue PTFE-coated steel nuts have a slippery surface to resist sticking during installation. They're resistant to chemicals and salt water.
