。[Claims for Utility Model Registration] (1) A polygonal hole is formed in the head of the bolt, and the bolt can be loosened or tightened by inserting a square wrench into the polygonal hole and rotating it. A bolt with a polygonal socket is provided with a blinding plate such that the blinding plate 5 is movably disposed within the polygonal hole so as to close the opening surface of the polygonal hole 3; A spring mounting hole 6 formed at the tip of the bolt located on the opposite side of the head of the bolt is formed along the axial direction of the bolt in order to communicate the polygonal hole 3 and the spring mounting hole 6. an actuating rod 8 having one end fixed to the back surface of the blind plate 5 and the other end disposed in the spring installation hole 6 through the through hole 4 as desired; A pressing spring 7 is installed in the spring installation hole 6 in order to press the rod 8 toward the head of the bolt, and a pressing spring 7 is installed in the spring installation hole 6 to prevent the pressing spring 7 from falling out of the spring installation hole 6. and a blind plug attached to the opening surface of the spring installation hole 6. A bolt with a polygonal hole equipped with a blind plate. (2) The bolt with a polygonal socket according to claim 1, wherein a drain discharge hole 9a is formed approximately at the center of the blind plug.
