Kind Code:

Abstract:
To solve the problems that an airplane, an automobile or the like is desired to reduce its weight, and also a bolt is desired to reduce its weight, and that it is difficult only for a bolt and a nut to prevent looseness resulting from vibration, and to utilize such a characteristic that although a cylindrical bolt is hard to bend, a tabular bolt bends in front-back directions with respect to a surface, to prevent looseness.SOLUTION: A nut is inserted into a bolt. A material 8 is fastened with the nut. After fastening, a screw tip 5 projecting from the nut is bent by a pair of pliers, so that the nut is locked to the bent screw part to prevent looseness. When a head part 3 is also bent, air resistance is reduced, and bumps are also made inconspicuous.SELECTED DRAWING: Figure 6
