Spring washers are mechanical components designed to provide a flexible connection between two parts. They are typically made from metal and have a curved shape that allows them to compress and expand under load. This flexibility helps maintain tension and prevents loosening of fasteners, such as bolts and screws, in various applications. These washers are commonly used in machinery, automotive, and construction industries. By absorbing shock and vibration, spring washers enhance the reliability of assemblies. They come in various sizes and materials, making them suitable for different environments and load requirements.
