Cap Nuts

In stock

Cap Nuts are a type of nut with a dome-shaped top. It secures and covers exposed threaded studs, rods, and bolt ends with a dome-like cap. This protects and secures the fastening component while providing a finished appearance to the exposed threaded end. The dome-shaped caps are designed to be readily grabbed and tightened by hand or wrench.

It works as a locking mechanism, preventing the nut from becoming loose due to vibration or movement. Our range includes Hex Cap Dome Nuts, which have a hexagonal nut shape with a dome or cap that encloses exterior threads. They are available with or without a moulded-in locking thread for applications requiring torque for a more secure assembly. Commonly utilised in automotive, industrial, and commercial applications.
