sw94-2Two distinct washer configurations are integrated in this single stamping to provide two distinct load and deflection stages. The vertical “wall” that results from the forming of this washer is greater that the material thickness in height. This is a load bearing wall that changes the inside-outside radius relationship of the two washer configurations and significantly increases total load-to-flatten capability. The Square Cone washer provides greater spring return and tension at minimum torque tolerances and has the strength to support maximum torque loading.

Tests have shown that a Square Cone washer will achieve the same clamp load as a standard conical washer at 30% less torque. In most applications, applied torque is used as a method of determining whether adequate clamp load has been developed in a joint. The Square Cone washer provides maximum uniformity in the torque to tension ratio. With its large deflection range, the Square Cone washer allows torque to develop gradually, eliminating the shock loading that causes installers to develop carpel tunnel syndrome.
