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.

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.
