From the state of the tool system 1 shown in FIG. 7, the worker moves the tool system 1 along the axial direction of the screw shaft X2 (rearward), thereby separating the tool system 1 and the member to be fastened X1. becomes. The second position of the marker 9 in the tool system 1 of Embodiment 1 is such that when the marker holder 4 moves backward from the member to be tightened X1, which is a nut, the marker 9 moves linearly from the member to be tightened X1 to the screw axis X2. This is the position where the tip portion 91 comes into contact with the tightened member X1 and the screw shaft X2.

FIG. 8 illustrates marking traces M1 remaining on the clamped member X1 and marking traces M2 remaining on the screw shaft X2 after the tool system 1 is separated from the clamped member X1. As shown in FIG. 8, the marking trace M1 and the marking trace M2 continue linearly from the rear surface X11 of the member to be fastened X1 to the peripheral surface X21 of the screw shaft X2. In other words, the marker holder 4 of Embodiment 1 can perform linear marking from the member to be fastened X1 to the screw shaft X2. Since the marker holder 4 is capable of linear marking, for example, during periodic inspections of fastening points, an operator can check the linear marking to determine whether or not the member to be fastened X1, which is a nut, is loosened. can be easily determined. That is, when the marking trace M1 of the member to be fastened X1 and the marking trace M2 of the screw shaft X2 do not follow linearly, the operator can easily recognize that the member to be fastened X1 is loosened.
