Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a bolt connecting nut used when connecting a coupling bolt such as a hanging bolt and a connecting bolt to an anchor bolt, and an anchor construction method in an electric construction, air conditioner construction, duct construction, and supply and drain water construction, with which the direction of the nut can be easily identified even at a dim site, even when the amount of a bolt screwed into the bolt connecting nut is different for each bolt or when a specification such as a screw diameter or a pitch is different for each bolt. SOLUTION: In the bolt connecting nut 1, bolts are screwed into both ends of the substantially cylindrical nut having a female screw hole 11 thereinside for connection. Through-holes 12a and 12b are provided at one end and the other end of the nut 1, penetrating from each of ends to predetermined length positions in the axial direction and a right-angle direction of the nut 1, and the diameters of each of the through-holes 12a, 12b are made different from each other.
