Metric Low-Strength Steel Cap Nuts
Often referred to as acorn nuts, these nuts have a smooth rounded head that covers and protects threads while providing a finished appearance. About half the strength of medium-strength steel cap nuts, use them in light duty fastening applications, such as securing access panels.
Zinc-plated steel cap nuts resist corrosion in wet environments.
Chrome-plated steel cap nuts have excellent resistance to chemicals and salt water and have a decorative metallic finish.

Metric Plastic Cap Nuts
Made from nylon 6/6, these cap nuts are chemical resistant, nonconductive, and lightweight. Also known as acorn nuts, they have a smooth rounded head that covers and protects threads while providing a finished appearance.

Metric Nylon-Insert Cap Locknuts
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. These nuts are reusable, but the nylon insert’s holding power decreases with each use. Also known as acorn nuts, they create a finished appearance and can reduce snagging on wires and insulation. Nuts meet DIN 986, an international standard for domed cap nut dimensions.
These nuts are made of strong and wear-resistant Class 6 steel. A zinc plating extends the life of the nut by protecting the inner steel from rust.
