Cap nuts, also called acorn nuts, are used to protect an exposed bolt end. This nut get it's named by the shape, which has a domed top to cover the threads for a more finished look. Cap nuts prevent stripping of screws and bolts on engines, machinery and wood frames so they can be easily removed and reused. They come in various materials, including brass, steel, stainless steel or nylon.
