Spring washers are widely used in mechanical devices to provide elastic support for fastening bolts or nuts to prevent loosening or reduce the impact of vibration on the connecting parts. Spring washers are usually made of spring steel or stainless steel and are flexible enough to absorb and disperse the pressure of the fastening force and prevent the bolts from loosening. They are often used in machinery, automobiles, aerospace and other industrial fields. If you need to use spring washers for specific projects, it is recommended that you contact a professional supplier to ensure that the appropriate specifications and materials are selected.
