- 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.
