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.
