Main purpose:
The main use of carbon steel single coil spring washers is to prevent the nut from loosening under the nut.
In mechanical design and production, adding spring washers is a simple and easy method to prevent nuts (or bolts) from automatically loosening.
Especially on equipment with vibration, such as bolts connecting motors to machine bases, spring washers are usually required to prevent nuts from
loosening due to vibration
