摘要：
A method of producing a nut having a drive area and a clamping area, and a screw tap for performing the method. A bore hole running through the clamping and drive areas is produced in a cylindrical manner. The screw tap is screwed into the cylindrical bore until a predetermined position is reached. The screw tap is successively provided, when seen in an axial direction from the front side thereof, with a centering/cutting section, an adjoining cutting section which is used to produce a conical internal screw thread section in the clamping area, and a cutting section which is used to produce a cylindrical internal screw thread section in the drive area.
