A nut threads onto the bolt shaft after placement of the washer thereof. The nut has flats on its front face that mate with the ears on the lock washer. As the nut is torqued onto the bolt during assembly, the ears of the lock washer deform back into the flats of the nut locking the washer to the nut.
