A cap nut is a nut with a dome-like finished top. They are used to cover exposed threaded stud, rod and bolt ends for safety and aesthetic reasons. Cap nuts are used on scores of structures and come in many sizes. Cap nuts are threaded like traditional nuts, making removal simple.
Locate the cap nut that needs to be removed.
Find pliers, a wrench, ratchet or another rotary device that will fit snugly around or match the cap nut.
Turn the rotary tool counterclockwise until the cap nut is loosened and removed.
