摘要： The invention relates to a method and a device for checking a screwed connection and to special screws to implement said method. The method is based on the utilization of a special screw (2) with a one-piece cored hole (5) pressing together two components with a prestress force. The method comprises the following steps: determining the original length of the special screw by measuring the length of the cored hole; determining the length of the special screw when stressed by measuring the distance from the head of the screw (7) to the bottom of the bore and comparing the measuring values of said lengths with predetermined data. According to predetermined criteria, it is determined whether sufficient prestress force has been applied or whether it is necessary to further tighten the screw. The device for checking the prestress force comprises the special screw (2) and a length measuring device (1) determining the distance from the base surface of the cored hole (5) to the screw head (7) and the distance between the front face of the core (4) of the cored hole to the screw head (7). The annular gap (5) of the cored hole can be filled with a material preventing penetration of dirt and humidity and having almost no influence on the extension of the screw. The invention can be preferably used for controlling a screw connection in industrial production, in workshop operations or for monitoring purposes in plant engineering.

摘要： The invention relates to a method and a device for producing and checking screwed connections that can be preferably used in assembly processes in industrial production, in workshop operations or for monitoring purposes in plant engineering demanding strict safety requirements. The invention also relates to special screws for implementing the inventive method. The invention is characterized by a special screw (1) having an additional thread (5) on the screw head (2), which prestresses the special screw (1) and retains the prestress force during screwing.

摘要： 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
