Extreme-Strength Steel Heavy Hex Nuts—Grade 2H
Because they’re about 10% wider and taller than standard hex nuts, these heavy hex nuts 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.
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.
Blue PTFE-coated steel nuts have a slippery surface to resist sticking during installation. They're resistant to chemicals and salt water.

Low-Strength Steel Heavy Hex Nuts
To distribute the load over a large area, these heavy hex nuts are about 10% wider and taller than standard hex nuts. They're about half the strength of medium-strength steel nuts and used for light duty fastening applications, such as securing access panels.
Zinc-plated steel nuts resist corrosion in wet environments.
Nuts that meet ASME B18.2.2 comply with standards for dimensions.
Nuts that meet SAE J995 comply with specifications for materials.

Super-Corrosion-Resistant 316 Stainless Steel
Heavy Hex Nuts for High-Pressure Applications
These nuts have excellent chemical resistance and can be used in saltwater environments. They're able to maintain their strength in high-pressure and high-temperature environments and are used with ASTM A193 bolts to fasten pressure tanks, valves, and flanges. Considered heavy hex nuts, they are about 10% wider and taller than standard hex nuts and distribute the load over a large area. Nuts may be mildly magnetic.
