Washers, or spring washers, are a subtype of washers. This thin plate is disk-shaped and has a hole in the middle Split lock washers, also known as spring washers, is vibration-resistant. Their shape is helical because the rings are split at one point. It has been well over 100 years since spring lock washers were first used. In many applications, they are still used with the belief that they will prevent the bolt from loosening. The Bolt Science Company conducted a series of tests comparing this washer to a plain nut by itself to illustrate its performance.
Spring Washer Operations:
Similar to a compression spring, a spring washer deflects under load. Spring washers with a greater height can handle more loads. There are two types of loads that spring washers endure: static and dynamic. Washers such as flat washers and spring washers are well known and frequently used. Because of their differences, they must be distinguished in practice, or else they will fail to fulfill their duty, and may cause harm.

Standard spring washer:
A spring washer is a left-hand helix that enables the thread to be tightened in a right-hand clockwise direction. Vibration is a primary concern when using Spring Washers. By compressing the washer when the fastener is tightened, tension is added and the loosening process is slowed down.
