Metric DIN 137 Curved & Waved Spring Lock Washers Specification Sheet
Metric DIN 137 Type A and B Spring Lock Washers are specialty spring lock washers â€“ Unlike standard split helical spring lock washers, the DIN 137 lock washers are uninterrupted formed disks in either a curved or waved configuration that are non-directional allowing the screw and or nut to be tightened in a clockwise or counter-clockwise manner. When compressed by tightening the nut, the DIN 137 lock washers exert a spring force between the tightened bolt and the substrate creating frictional resistance to rotation.
