When the center of the screw hole N is displaced from the center of the stud bolt B, when the chamfer of the screw hole N is small, or when the thread of the tip side screw portion B2 of the stud bolt B is crushed, as shown in FIG. In such a case, even when the tightening machine 51 is rotated, the screw is not screwed into the screw hole N of the cylinder head W and idles, while the base screw portion B1 and the female screw portion A of the tightening machine 51 are rotated. Or between the semi-circular pins C, the screwed state becomes hard and becomes a locked state, and the stud bolt B is stuck to the tightening machine 51 even if the tightening machine 51 is reversed and retracted with the intention of implanting the stud bolt B. There was a problem of retreating together while standing.
