These locknuts have an irregularly shaped thread in the middle of the nut that grips the bolt for a stronger hold than nylon-insert locknuts. Also known as reversible locknuts, they can be threaded on from either end. They're about three times stronger than low-strength steel locknuts. The strength of the bolt should match the strength of the nut to prevent damaging threads. They're not reusable.
Black-oxide steel locknuts have a dark surface color and are mildly corrosion resistant in dry environments.
Zinc yellow-chromate plated steel locknuts resist corrosion in wet environments.
Zinc-aluminum coated steel locknuts are more corrosion resistant in wet environments than zinc yellow-chromate plated steel locknuts.

These locknuts tighten when turned to the left. They have an irregularly shaped thread in the middle of the nut that grips the bolt for a stronger hold than nylon-insert locknuts. Also known as reversible locknuts, they can be threaded on from either end. They're about three times stronger than low-strength steel locknuts. The strength of the bolt should match the strength of the nut to prevent damaging threads. They're not reusable. A zinc plating provides corrosion resistance in wet environments.

These locknuts have excellent resistance to chemicals and salt water. They have an irregularly shaped thread in the middle of the nut that grips the bolt for a stronger hold than nylon-insert locknuts. Also known as reversible locknuts, they can be threaded on from either end. The strength of the bolt should match the strength of the nut to prevent damaging threads. They're not reusable.
