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

These locknuts have an irregularly shaped thread at the top of the nut that grips the bolt for a stronger hold than nylon-insert locknuts. They thread on from the bottom of the nut, allowing more threads to engage the bolt before tightening for easier installation than center-lock distorted thread locknuts. The strength of the bolt should match the strength of the nut to prevent damaging threads. They're not reusable. About half the strength of medium-strength steel locknuts, use them in light duty fastening applications, such as securing access panels.
