Brass Cap Nuts
These cap nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic. Also known as acorn nuts, they have a smooth rounded head that covers and protects threads while providing a finished appearance. All have excellent resistance to chemicals and salt water and have a decorative metallic finish.
