Conical Belleville washers are used primarily to add pre-load to a nut and bolt assembly. When placed under the head of the bolt, they add a layer of force between the bolt head and the installation surface. This serves as a resistance to vibration to prevent accidental loosening, which is why these washers are commonly found on automobiles, airplanes, and heavy machinery.
