PROBLEM TO BE SOLVED: To facilitate a female screw body installation operation by allowing a number of female screw bodies to be simultaneously laid in a state just before screwing in which they are located above male screw bodies with male screw of electronic equipment. SOLUTION: The tool JG includes a lower plate 20 and an upper plate 30. Each of the plates 20 and 30 includes a plurality of lower insert holes 21 or upper insert holes 31. Each alignment of the holes 21 or 31 in a plan view is matched to the alignment in a plan view of shaft parts 11 to which nuts 12 are to be screwed. When the nuts 12 are fitted into all the upper insert holes 31 in a state where the plate 30 laminated and placed on an upper surface 20e of the plate 20 is located at a right moving limit position with the position of each lower insert hole 21 being matched to each shaft part 11, and the plate 30 is slid to a left moving limit position, each nut 12 naturally falls from the upper insert hole 31 through the corresponding lower insert hole 21 and located on a tip 11b of each shaft part 11.
