置。 A screw length determination device for tightening screws at multiple locations on a single workpiece using a screw tightener, which increases the torque from startup based on a startup signal and a torque up signal output from the screw driver. A screw tightening time measurement means that measures the time up to 30 seconds for each screw individually as the screw tightening time, and the next reference time is calculated by dividing the sum of the previous reference time and the current measured screw tightening time by 2. a reference time setting means for setting the actual screw tightening time, a comparison means for comparing the actual screw tightening time with the reference time, and a determination means for determining whether the screw length is good or bad based on the comparison result by the comparison means. A screw length determination device.
