Spring washers are a type of washer with a split lock or split ring design. These types of washers are designed to be fitted in between bolts, nuts, or other washers and surface panels, and thanks to their unique construction, they absorb the vibrations from the bearing surface that might loosen the fasteners over time. They are super versatile and can be used for a wide range of applications and different environments, but spring washers can most commonly be found in machinery with high levels of vibrations like industrial machinery or domestic appliances like washing machines and tumble driers.
