Low-Strength Steel Thin Nylon-Insert Locknuts
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 known as black luster locknuts.

Low-Strength Steel Extra-Wide Thin Nylon-Insert Locknuts
These locknuts are about half the height and 10% wider than standard nylon-insert locknuts. Use them in light duty low-clearance applications or jam one against an extra-wide 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.
