A retaining and locking washer for the union of nut and screw, characterized in that it has a radial cut; because one of the ends of the division produced by this radial cut, properly tuned, is moved to a different plane from that of the washer, and because this sharp and displaced edge is intended, once the nut on the screw is screwed to its position of final tightening, and also threaded the lock washer to make contact with the nut to be blocked, to be introduced under pressure in the angular space determined by the wall of the thread closest to the nut and the adjacent face of this, wedging itself in it and preventing the unwanted recoil of the nut.
