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.
