About 10% wider and taller than standard hex nuts, these metric-sized heavy hex nuts distribute the load over a large area. 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.

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 heavy hex nut to hold it in place. They're often used in conjunction with a heavy hex nut to fasten Grade 9 bolts in heavy machinery, such as earth-moving equipment.

Zinc-plated steel nuts resist corrosion in wet environments.
