Almost all torque drivers evaluate and control their fastening screws by the fastening torque. However, it is difficult to measure fastening torque, since a large impulsive torque acts at the moment a screw head touches the work. The impulsive torque varies with fastening conditions and often goes over a setting torque. That is, it can be said impossible to measure the fastening torque correctly by the peak mode of a torque meter. Therefore, the change in rotation angle of a bit with time is studied as well as the torque. As a result, it was found that screws continue to rotate and fasten the work, even if the impulsive torque surpasses the setting torque. Using a driver FED II 10 K, we studied how fast we can revolve the bit.
