This disclosure relates to a me-piece,' self-locking screw wherein a cupped or Belleville-type washer is integrally formed with the head of the screw to maintain a preload on the screw when assembled to resist the tendency of the screw to loosen due to vibration. The one-piece design also simplif ies assembly operations.
