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 High-Strength Steel Cap Nuts—Class 10
Often referred to as acorn nuts, these nuts have a smooth rounded head that covers and protects threads while providing a finished appearance. They're about 25% stronger than medium-strength steel cap nuts and comparable in strength to Class 10.9 bolts. A zinc plating provides corrosion resistance in wet environments.

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.

Sanitary Low-Profile Cap Nuts
Certified by EHEDG (European Hygienic Engineering and Design Group) to meet sanitary design standards, these cap nuts fit into tight spaces to cover and seal exposed threads in your food processing facility. Also known as acorn nuts, they’re at least 20% shorter than standard cap nuts. Made from 316 stainless steel, these nuts won’t corrode from frequent washdowns with water or harsh cleaners. They are self-draining, meaning that they don’t have horizontal surfaces, so liquids and debris will drain off completely. They also have extremely smooth sides and rounded edges to eliminate crevices where bacteria could grow.
The silicone seal at the base of the nut keeps contaminants off the threads and prevents an unsanitary metal-to-metal connection. It’s made with metal and chemical additives, so you can find it with a metal detector or X-ray machine if it falls into your line. This helps you comply with Hazard Analysis and Critical Control Point (HACCP) programs to keep contaminated food from leaving your facility. The seal is also FDA compliant, so it’s safe for direct contact with food.

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.
