Abstract: A method of making a shaft abutment screw, especially for axial engagement with an armature shaft of an electric motor, includes the following steps:(a) pressing out a flat mild steel blank, (b) subjecting the blank to a drawing operation so as to form a hollow component comprising a generally flat radial base wall and a generally cylindrical skirt portion extending from the base wall and describing a screw driving socket within it, (c) machining a screw thread on the outside of the skirt portion, and then (d) nitriding the component. A shaft abutment screw having a flat base portion joined to an externally threaded cylindrical skirt portion, within which a hexagonal screw driving socket is formed, is also described per se. The invention is applicable especially to motorised reduction gear units for driving motor vehicle screen wipers for windshields and rear windows.
