きます。[Means for solving the problem] To solve this problem, it is only necessary to cover and tighten the cap nut on the full screw bolt, and then remove the cap nut, but when removing the cap nut, the bolt comes off together. Therefore, according to the present invention, only the cap nut can be removed by making the surface of the cap portion of the cap nut that the bolt comes into contact smaller than the bottom face of the female screw into which the bolt is to be built.

A convex portion (2) is provided inside a bag of a cap nut (1), and a stud bolt (3) is screwed into the cap nut (1). The other end of (3) is turned into the female screw (5) of the bolt mounting part (4), and the hexagonal pin (6) of the cap nut (1)
When is turned by an electric drill or the like, the built-in bolt (3) is pressed by the convex part (2) and pressed against the bottom (7) of the female screw (5) of the bolt built-in part (4). When the cap nut (1) is turned in reverse to remove the cap nut (1), the press-contact surface of the stud bolt (3) is raised from the convex part (2) of the cap nut (1) to the bottom (7) of the female screw (5). The contact surface is larger, and the cap nut (1) can be removed without loosening the built-in bolt (3) due to the difference in friction.

め極めて安価に作ることが出来ます。According to the present invention, in order to mount a conventional full screw bolt,
There are tools such as pliers or double nuts, then remove the nut after tightening, and also incorporate rollers inside.However, the pliers and roller tools will damage the threads, and double nuts will remove the nuts one by one. It must be troublesome. Bolts may be loosened when unscrewed with ordinary cap nuts, but the cap nuts of the present invention protrude from the center of the bag, so the bolts may loosen when the cap nut is removed due to the difference in the pressure contact surfaces of the bolts to be built. There is none. Because of the above structure, it can be made very inexpensively.
