装置。 A number of nut runners are installed in parallel to tighten a number of nuts at the same time, and a nut runner is interposed between the output shaft of the nut runner and the socket fitted into the nut, and the nut runner tightens the nuts to a preset lower limit torque value. A torque lower limit monitoring device is equipped with a switch that emits a signal when the torque is reached, and a torque lower limit monitoring device that operates based on the signal generated by the switch and is energized when the lower torque limit of the nut tightened by each nut runner reaches the set value. an alarm device that is energized to indicate that tightening is incomplete when the lower limit tightening torque of at least one nut does not reach a set value despite the operation of the nut runner; and an abnormality detection circuit that energizes the switch provided in the torque lower limit monitoring device of each nut runner for a short period of time after startup, and activates the alarm device when any switch is improperly closed. A multi-axis nut runner device characterized by:
