These metric nuts are about half the strength of medium-strength steel cap nuts. Use them in light duty fastening applications, such as securing access panels.

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

Known for their strength, these steel cap nuts have a black-oxide finish to resist corrosion in dry environments.

A nylon insert on these metric nuts prevents vibration from loosening them, and a domed head protects the threads at the end of the bolt from damage and debris.

Cap nuts cover and protect threads while providing a finished appearance.
