Claims

[Claim for Utility Model Registration] The tip of a bolt that is screwed into a screw hole provided through a pair of washers is screwed into a nut via a washer, and the nut is rotated by a motor-driven fastener. In a bolt tightening device that tightens a bolt between a pair of washers, there is an axial force detector that detects the axial force of the bolt from the axial force that acts between the pair of washers, and a bolt tightening device that detects the axial force of the bolt from the axial force that acts between the pair of washers. a torque detector that detects the torque acting on the bolt, a rotation angle detector that detects the rotation angle of the nut in conjunction with the rotation of the fastener, and a pair of torque detectors that contact the head and tip of the bolt from the axial direction, respectively. An elongation detector that detects the elongation of the bolt from the displacement of the contact, a torque coefficient calculation circuit that calculates the torque increase coefficient with respect to the axial force, and a torque gradient coefficient calculation circuit that calculates the torque increase coefficient with respect to the rotation angle. At least a bolt tightening test device.
