METHOD AND ARRANGEMENT FOR TIGHTENING A SCREW CONNECTION

Abstract: a method for tightening a screw connection between a first and a second component which are equipped with interacting threads including rotating one of the threads to tighten the screw connection, successively detecting the angle of rotation via an angle sensor and detecting the torque via a torque sensor during tightening of the screw connection, evaluating the signals of the angle sensor and the torque sensor via an electronic processing device to determine one or more characteristic features of the signals and comparing the one or more characteristic features with one or more reference values, identifying via the electronic processing device on the basis of the comparison whether an intermediate element is inserted and clamped as intended between the first and second components, and emitting via the electronic processing device a fault notification when the result of the comparison is that the intermediate element is absent or is inserted incorrectly.
