As the name suggests, the cap nut is a hexagonal nut with a cover. The function of this cover is to tighten the exposed part on the outside to prevent moisture or other corrosive substances from entering inside, thereby playing an anti-rust role and thus increasing the service life of the nut itself and the connecting parts.
