摘要： A fastening tool includes a bit holding portion configured to hold a driver bit engageable with a screw and that is rotatable in a circumferential direction and movable in an axial direction of the driver bit, a motor configured to rotate the bit holding portion, a controller configured to control the motor, and a detector configured to detect a state of the motor. In a state where the screw engaged with the driver bit is fastened to a fastening target, the controller determines whether the driver bit and the screw are disengaged based on the state of the motor detected by the detector and stops the rotation of the motor in a case where the controller determines that the driver bit and the screw are disengaged.
