Split Spring Washers Curved

Description

These are specialty spring lock washers – They are split metal rings that are bent into a curved (Type A) configuration.

Unlike standard split helical spring lock washers, the DIN 128 lock washers are non-directionally specific allowing the screw and or nut to be tightened in a clockwise or counter-clockwise manner.

When compressed by tightening the nut, the DIN 128 lock washer exert a spring force between the tightened bolt and the substrate creating frictional resistance to rotation. The lock is created by the friction the lock washer generates between the screw head and the base and between the threads.
