These cap nuts are about 20% wider and taller than standard cap nuts and have high sides to provide a larger area for your wrench to grip. Also known as acorn nuts, a smooth rounded head covers and protects threads while providing a finished appearance. They have a black-oxide finish that provides mild corrosion resistance in dry environments.
