A Cap Nut is a nut with a special shape that resembles a hat, so it is also called a cap nut. It is usually made of metal material and has internal threads for use with Bolts.
The cap nut holds the Bolt in place and provides additional protection. It prevents bolts from loosening or falling off, and prevents external objects from entering the threaded holes, thus acting as a seal. The cap nut can also provide certain protection to prevent the bolt from external impact or damage.
Cap nuts are often used where additional protection and sealing are required, such as in mechanical equipment, automobiles, aerospace and other fields. They can choose different materials and surface treatments according to different needs and application environments to improve their corrosion resistance and service life.
In summary, a cap nut is a nut with a special shape that can provide additional protection and sealing and is widely used in various mechanical equipment and engineering projects.
