Abstract

PROBLEM TO BE SOLVED: To solve cost and strength suitability problems in weight reduction of a main body based on cutting work in a head part or substitution in a material of light metal, plastic and the like and problems of matching with a conventional construction method when the main body shape is changed in weight reduction of a bolt. SOLUTION: When the shape of the bolt head part and a thread part is formed into a hexagram or a regular triangle, the weight can be greatly reduced, and compliance with constructional connection with a conventional tool, a receiver and the like can be accomplished.

行にも対応します。A polygonal prism inscribed in a cylinder, for example, a regular triangular prism or a star-shaped hexagram column, is considered as a main axis with respect to a conventional cylindrical shape, which is the shape of a screw portion, and the ridge portion of the prism is formed on the polygonal prism. Significant reduction in weight can be achieved by screw processing, and it can also be used for joining with conventional nuts. In addition, the equilateral triangular shape and hexagram shape of the head are not only effective for weight reduction, but also can be applied with conventional tightening tools.

現できます。DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the embodiments shown in FIGS. 1 to 4. The equilateral triangle of the bolt head (1) in FIG. 1 has three regular hexagonal vertices of the head of the conventional hexagonal bolt JISB1180. This allows the use of a socket wrench and a ratchet wrench for a bolt tightening tool. Similarly, the hexagram of the bolt head (3) in FIG. 3 corresponds to this by capturing six vertices of a regular hexagon. The screw part (2) in FIG. 1 is formed by screwing three ridges of a regular triangular prism inscribed in the circumference of the conventional hexagon bolt with a nominal screw diameter, and the screw part of the hexagram column in FIG. (4) is threaded into six ridges. As described above, by changing the shape of the bolt head (1) in Fig. 1 and the bolt screw part (2) in Fig. 1 to an equilateral triangular structure or hexagram structure, it is possible to significantly reduce the weight of the bolt.
