Joining systems for Function critical screwing

For function-critical screwing corded handheld nutrunners, corded handheld electric screwdrivers and fixture screwdrivers are used. The torque generator operates with an algorithm of motor current, frequency, voltage and temperature. The monitoring is not redundant, as is the case with safety-critical screw connections. Furthermore, an angle sensor is integrated. Torque monitoring is also usable. Angle steps of 36 degrees are typical. The speed control is infinitely variable. The usual angular misalignment defaults +/- 7.5% sigma over 6 sigma.
