PURPOSE: To use a single nut for a plurality of normal diameters by arranging female screws of different normal diameters in the surfaces of a polyhedron. CONSTITUTION: A regular octahedron nut body 5 is made of a material such as steel or plastics. A female screw of M6, a female screw of M5, a female screw of M4 and a female screw of M3 are chased respectively in a first surface 5a, a second surface 5b, a third surface 5c and a fourth surface 5d. The screws go through to the surfaces of the opposite sides. In this way, a single nut can have four female screws of different normal diameters. If different female screws are chased respectively in the various surfaces with the screws not going through to the opposite sides, it is possible for the nut to have eight normal diameters.
