These locknuts are about half the height of standard nylon-insert locknuts. Use them in light duty low-clearance applications or jam one against a hex nut to hold it in place. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use.

Black ultra-corrosion-resistant coated steel nuts are more corrosion resistant than zinc-plated nuts in wet environments. They're also black luster.

These locknuts have a nylon insert that grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use. About half the strength of medium-strength steel locknuts, they're for light duty fastening applications, such as securing access panels.

Also known as acorn nuts, these nuts have a smooth rounded head that covers and protects threads while providing a finished appearance. About half the strength of medium-strength steel cap nuts, use them in light duty fastening applications, such as securing access panels.

Black ultra-corrosion-resistant coated steel cap nuts have excellent resistance to chemicals and salt water.
