Abstract:
A process for checking when tightening a threaded fastener that it has been tightened on the complete threads of the fastener. In order to do this the process comprises detecting different gradients in a tightening graph representing torque as a function of another parameter and comparing each gradient with predetermined values. According to the portions of graph detected and their gradient values it is possible to determine whether tightening is correct and has taken place on the complete threads of the fastener, or if not it is possible to identify a cause of failure.
