"IMPROVEMENTS IN THE MANUFACTURE OF SAFETY NUTS" which are characterized by a washer in the form of an elastic constitution sleeve whose axial dimension comprises several threads and whose internal cylindrical surface is smooth and of a smaller diameter than the external diameter of the screw, which housed in a face opposite the pressure face of one of the internal thread elements on one of the faces of the pieces to be joined by the screw, is compressed against the screw threads of the screw, being embedded between them and originating a friction that opposes the relative rotational movement between both threaded elements thus preventing accidental unscrewing.
