HS washers
This screw locking element is basically a tension washer with a smaller outer diameter than according to DIN 6796. A special feature of this washer is its slightly curved shape. This achieves a progressive characteristic curve that makes it possible to achieve the same spring forces as the clamping disks according to DIN 6796 despite smaller external dimensions. This disk is mainly used when there is not enough installation space available for standardized clamping disks.
