A cap nut is a type of nut that covers exposed studs, rods, and bolt ends with a dome-shaped cap, which provides security and a complete appearance to the exposed threaded ends. The function of the cap of Cap Nuts is to cover the exposed part of the outer side of the fastener to prevent moisture or other corrosive substances from entering the inside to prevent rust, thereby improving the service life of itself and the connector. 

Cap Nuts can also be composed of various materials, such as stainless steel, which is almost as strong as steel, has good corrosion resistance, and will not rust in outdoor or washdown environments. Corrosion-resistant material is combined with the cap of Cap Nuts to make it last longer. 

Since Cap Nuts' domes provide a more polished look, they are widely used on products that need to be exposed to surfaces. Because of its corrosion resistance, it is accepted by most mechanical equipment, such as cameras, glasses, clocks, electronics, televisions, electrical products, musical instruments, furniture and a series of industrial products.
