摘要： A fastening tool includes: a bit holding portion which detachably holds a driver bit and is configured to rotate in a circumferential direction of the driver bit and move in an axial direction of the driver bit; a motor configured to perform at least one of rotation of the bit holding portion and movement of the bit holding portion along the axial direction; and a control unit configured to control a position of the bit holding portion along the axial direction by a rotation amount of the motor. The control unit is configured to stop rotation of the motor based on a load applied to the motor rotated in one direction of moving the bit holding portion in a direction approaching a fastening target.
