載の締着ボルト。[Scope of Claim for Utility Model Registration] (1) A bolt body with a circular head and a locking means on the outside of the head of the bolt body that is fitted and locked so that it can be rotated with a special wrench equipped with a magnet. a magnetic force-responsive clutch mechanism that is assembled between the head cap and the bolt body and connects the bolt body and the head cap so that they can rotate together only when the head cap is rotated with a special wrench equipped with a magnet. A fastening bolt comprising: (2) The bolt body has a circular head, a flange for fastening members under the head, and a bolt thread, and a clutch assembly hole is recessed in the end face of the circular head, and the head cap is A circular fitting hole is rotatably fitted to the outside of the head of the bolt body, and a locking means is provided to prevent the bolt from coming off from the head of the body. The clutch mechanism is formed of a non-magnetic lid having a recessed clutch connecting hole that matches the mounting hole, and allows magnetic force to pass through but is not magnetized, and the clutch mechanism is capable of attracting a magnet built into the clutch mounting hole of the bolt body so as to be movable in and out. When the head cap is rotated with a special wrench equipped with a magnet, the movable clutch is pulled up to a state where it is partially fitted into the clutch connection hole that matches the clutch installation hole by the magnetic attraction action of the wrench magnet. 2. The fastening bolt according to claim 1, wherein the fastening bolt is configured such that the head cap and the bolt body can be integrally rotatably connected. (3) The head cap is a hexagonal cap nut made of nonferrous metal, and the hexagonal cap nut is rotatable by fitting the hexagonal hole of a special wrench with a magnet to the outside of the hexagonal cap nut. The fastening bolt according to claim 2.
