Heavy Duty Hexagonal Nut Black Steel 3/4-10 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 earthmoving equipment.

Black steel nuts have a noir surface color and are mildly corrosion resistant in dry environments. The nuts have a 3/4-10 thread.
