Screw lock, in the form of a spring of a die-cut metal plate, with a solid, annular core region, having an outer edge, an inner edge, an upper face and a lower face, with ribs running approximately radially disposed, densely arranged side by side at regular intervals, which in cross section, are approximately triangular in shape and both the upper face and the lower face are provided in at least partial areas, characterized in that they are perpendicular to the axis central, in the area of the outer edge is essentially greater than the distance in the area of the inner edge and because this distance decreases constantly from the reach of the outer edge to the reach of the inner edge.
