Hexagon Domed Cap Nuts

A cap nut is a fixture with one side of a hexagon nut covered with metal in a dome shape. The structure that tightened bolts and screws do not expose the tip is both safe and decorative, and is often used to secure park playground equipment. The main material is stainless steel or iron. Depending on the type, chrome, unichrome, and trivalent chromate with low environmental impact are surface treated with various processing solutions, and some types of “dough” are not treated. Care must be taken when fixing, as it may cause damage or loosening if not tightened properly.
