The invention concerns a method of producing specific screw connections, two components being urged against each other with predetermined pretension by means of a screw which is rotated by a screwing device which can be regulated, and the screw producing an acoustic emission. The invention is characterized by the following steps: detection of the acoustic emission which is generated in the screw during an actual screwing process; and comparison of the detected acoustic emission occurring during the actual screwing process with predetermined stored data, it being determined according to predetermined criteria whether the screwing process is proceeding correctly. The method can preferably be used in assembly processes in industrial production.
