Improved washer, which has the purpose of permanently maintaining indefinitely the tightening of a screw, essentially characterized in that it is constituted by the functional combination of two identical parts, annular, each of which has on one of its faces a plurality of teeth perimetral, with a sawtooth profile, each of which determines a straight staggering and a considerably prolonged and low inclination plane, so that when both pieces are coupled through their toothed faces, the special configuration of their teeth allows the relative rotation of one with respect to another in direction of tightening for the screw, making it impossible to rotate relative to the opposite direction.
