A spring washer, also known as a spring ring, is a type of ring-shaped washer with a helical split. Its function is to apply spring pressure to bolt/nut connections, preventing loosening due to vibration or dynamic loads.
Spring rings are widely used in construction, automotive, industrial machinery, and engineering equipment that require more secure and shock-resistant connections.
