These nuts are about 25% stronger than medium-strength steel nuts.

Zinc yellow-chromate plated steel nuts resist corrosion in wet environments.

Zinc-aluminum coated steel nuts are more corrosion resistant in wet environments than zinc-plated steel nuts. They're also known as ultra coat and armor coat nuts.

Black-Oxide steel nuts have a dark surface color and are mildly corrosion resistant in dry environments.
