• Made from 304 stainless steel, these cap nuts have good chemical resistance and may be mildly magnetic. Also known as acorn nuts, these nuts have a smooth rounded head that covers and protects threads while providing a finished appearance

• Made from 316 stainless steel, these nuts have excellent resistance to chemicals and salt water. Also known as acorn nuts, these nuts have a smooth rounded head that covers and protects threads while providing a finished appearance. They may be mildly magnetic.

• 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.

• 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.
