The Square Cone washer (Square Dome) absorbs high installation torques, generates and sustains tension, distributes the load and spans oversize holes. Replaces three parts: screw, flat washer and helical washer, in many applications.

The unique washer on this assembly combines the tension generating characteristics of a spring washer with the locking tension of the helical washer to increase shock absorption and vibration resistance.
