Locking Washer

A locking washer, also known as a lock washer or split washer, is a type of washer designed to prevent loosening or rotation of fasteners, such as nuts and bolts, due to vibration or other external forces. Locking washers typically have a split or bent shape that creates spring tension when compressed between the fastener and the surface it’s being tightened against. This tension adds resistance to loosening, helping to maintain a secure and tight connection. Locking washers are widely used in various industries, including automotive, machinery, construction, and aerospace
