Dome Nuts

Dome nuts (also called cap nuts or acorn nuts) feature a closed, rounded top that covers the exposed end of a bolt or threaded rod, protecting the thread from damage and providing a neat, finished appearance. They also eliminate any sharp, protruding thread ends that could cause injury.

Available in BZP and stainless steel finishes in a range of metric sizes. Commonly used in furniture, automotive trim, and anywhere a tidy, professional finish is required.

  • Sizes: M6, M8, M10, M12
  • Covers exposed thread ends for a clean finish
  • Prevents thread damage and injury from sharp threads
  • Finishes: BZP and A4 stainless
  • Metric coarse thread
