Cap Nuts

Conceal and protect protruding screw threads while fastening parts together. Also known as acorn nuts, they have a smooth, rounded head that creates a finished look.

• Standard— The most commonly used cap nuts.
• High— Cover extra-long screws without cutting them.
• High Heavy— Large gripping area keeps wrenches from slipping off as you tighten.
• Open End— Thread onto screws of any length.
• Threadlocker— A nylon patch on the threads resists loosening from mild vibration.
• Nylon Insert— A nylon insert prevents loosening from moderate vibration.
• Distorted Thread— Irregularly shaped threads grip better than a nylon insert.
• Sanitary / Sealing— Crevice-free with a Buna-N seal for sanitary or sealed applications.
