Metric Spring Lock Washer
Metric spring lock washers are also known as Helical spring split lock washers, Type B. They are split metal rings that are bent into a helical shape and the ends are squared and straight. Commonly used with Metric hex nuts and Metric hex bolts, split lock washers will create a spring force between the bolt and the nut which will resist rotation and create a secure lock in application.
