Cap Nuts

In stock

Cap Nuts, also known as a Blind Nut or a Crown Nut, is a nut that has a domed end on one side. The Domed Cap Nut is used to cover exposed threaded stud, rod and bolt ends with a dome-like cap. This offers protection and safety to the fastening assembly, while also creating a finished appearance to the exposed threaded end.

Our range is made up from Hex Cap Dome Nuts that feature a hexagonal nut shape with the dome or cap that encloses external threads. They are offered with or without a molded-in locking thread for applications which require torque for a more secure assembly.

  • Material: Nylon 6/6
  • Colors: Natural and Black
  • Flame resistance rating UL94 V2.
