Lock washer for nut and screw unit, characterized in that it is provided with an arched tongue, one of its lateral edges is constituted by the very edge of the bore of the washer, and the other by a concentric arc-shaped separation cut same, originated from a partial radial cut that starting at the inner edge of the washer, extends part of the width of this, whose tongue is slightly sharp towards its free end, or is blunt; because said end is displaced out of the plane of the washer and because it is intended, once the nut on the screw is screwed to its definitive position of tightening, and also threaded the washer until making contact with the nut, to be introduced under pressure in the angular space formed between the thread that is closest to the nut and the plane of it, wedging in it and thus preventing the recoil movement of the nut.
