An improved device for fastening screws, essentially characterized in that it is constituted by a flat washer of convenient shape, which has in its central middle part a recess whose configuration corresponds exactly to that of the neck of the application screw, with the purpose provided that by this adjustment the rotation of the screw is prevented but not its displacement in its introduction or extraction, the washer comprising some rear holders provided peripherally and in a position perpendicular to its base, which represent the anchoring means on the application surface.
