High-Strength Super-Corrosion-Resistant 316 Stainless
Steel Hex Nuts for High-Pressure Applications
Hardened for added strength, 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. Nuts may be mildly magnetic.

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.
PTFE-coated steel nuts have a slippery surface to resist sticking during installation. They're resistant to chemicals and salt water.

Metric Extreme-Strength Steel Extra-Wide Hex Nuts—Grade 2H
About 10% wider and taller than standard hex nuts, these nuts distribute the load over a large area. They're also known as heavy hex nuts. Grade 2H nuts are comparable in strength to Class 12.9 bolts. They're about 20% stronger than high-strength steel nuts and are used in heavy machinery, such as earth-moving equipment.
Fine threads are closely spaced to prevent loosening from vibration.

18-8 Stainless Steel Extra-Wide Hex
Nuts for High-Pressure Applications
These nuts have good chemical resistance and may be mildly magnetic. They maintain their strength in high-pressure and high-temperature environments and are used with ASTM A193 bolts to fasten pressure tanks, valves, and flanges. 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.

Super-Corrosion-Resistant 316 Stainless Steel
Extra-Wide 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. 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. Nuts may be mildly magnetic.

Extreme-Strength Steel Extra-Wide Thin Hex Nuts—Grade 2H
Also known as heavy jam nuts, these are about half the height and 10% wider than standard hex nuts. Use them in low-clearance applications or jam one against another extra-wide hex nut to hold it in place. They're often used in conjunction with an extra-wide hex nut to fasten Grade 9 bolts in heavy machinery, such as earth-moving equipment.
Zinc-plated steel nuts resist corrosion in wet environments.
