DIN 6797 Internal tooth lock washer Form J
External tooth lock washers manufactured according to DIN 6797 allow the immobilization of fasteners such as bolts and screws which are subject to vibrations while maintaining uniform tightening torque in any mechanical electrical or electronic application.
Form J is particularly recommended when the angle of the internal chamfer of the head of the bolt or screw is pronounced and in all cases where the head of the screw or bolt is smaller than the diameter of the washer.
This washer should also be used when the surface of the fastener is irregular or convex.
