Washers are a common component found in various assemblies, and they regularly come in the form of a thin, disk-shaped plate with a hole cut out of their center. While the primary use of a washer is to distribute the load of a fastener, such components may also act as a spacer, spring, wear pad, locking element, vibration reducer, and more. Washers come in many forms, plain, spring, and locking washers being the most common variations. Spring washers in particular are quite beneficial for applications in which vibration is a concern, featuring axial flexibility and fastener security.
