Wedge-locking washer pairs are specified for applications where maintaining clamp load under vibration is important. Selection should be based on the exact bolted-joint design, thread size, bolt strength class, mating surface, tightening method and the selected washer manufacturer's instructions. A wedge-lock washer is not a substitute for checking the joint's required preload.
