A Cap Nut, also known as an Acorn Nut or Dome Nut, is an internally threaded fastener with a rounded, dome-shaped top. The enclosed design covers the exposed end of a bolt, screw, or threaded stud, providing a neat finished appearance while helping protect the exposed thread.
Cap Nuts are commonly used where both fastening and protection are important. The domed head helps reduce direct contact with sharp or protruding threads and can also help protect nearby surfaces from scratches or damage.

Protection and Appearance
The enclosed dome design of a Cap Nut provides an additional layer of protection around the exposed end of a fastener. This can help reduce the possibility of accidental contact with sharp thread ends and protect nearby components from direct contact.
