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.
