We have studied the process of fastening screws by use of a torque meter HP-10 (HIOS) whose response is 600 Hz. However, it was found that there are some problems as to this torque meter. 1) HP-10 is equipped of an integrator of the time constant 23 ms to stabilize torque values. 2) The peak mode of HP-10 doesn't hold a fast peak shorter than 1.7 ms. Therefore, we make torque meters with torqueducers BTSX16Z and TD001, and compare the efficiency of 3 torque meters. Some interesting phenomena were found especially in case of the torque meter using TD001 which guarantees the high response of 3.4 kHz. It was also found that the evaluation of fastening screws using torque meters is one thing and the real fastening screws is the other thing. In the evaluation of fastening screws, the interaction of torque meter with screw, bit, and work must be taken into account.
