Low-Strength Steel Square Nuts
Large flat sides make these nuts easy to grip with a wrench and keep them from rotating in channels and square holes. About half the strength of medium-strength steel square nuts, use them in light duty fastening applications, such as securing access panels.
Zinc-plated steel square nuts resist corrosion in wet environments.
