Reference numeral 1 designates a nut in which a female screw 3 is carved toward the back from the threaded surface 2 side of the nut 1 to approximately the middle position of the depth of the nut 1. 4, a male screw entry hole 4 having a diameter slightly larger than the root diameter of the female screw 3 is bored on the back side of the female screw 3 (right side in FIG. 1). Reference numeral 5 designates a male screw that is screwed into the female screw 3 formed on the tip side of the bolt 6 (on the right side in FIG. 1). Reference numeral 7 denotes a female screw entry shaft portion provided inside the male screw 5 (on the left side in FIG. 1), and is formed into a cylindrical shape with a diameter slightly smaller than the inside diameter of the female screw 3. Reference numeral 8 denotes a locking shaft portion provided between the head 9 of the bolt 6 and the female screw entry shaft portion 7, and is formed into a cylindrical shape with a desired length of the locking portion.

る。(Function) Since the present invention has the above-described configuration, when locking, for example, insert the lock shaft part 8 of the present invention into the opening/closing part A of a container, etc., and insert the female thread 3 of the nut 1 into the male thread 5 of the bolt 6. After screwing together like normal bolts and nuts, and after the male screw 5 passes through the female screw 3, the male screw 5 is further inserted into the male screw entry hole 4 located at the back of the nut 1. The female screw 3 advances up to the female screw entry shaft portion 7, and as shown in FIG. 2, the screw portions become unscrewed from each other. In this state, screw in the screw surface 2 in the direction shown by the arrow (towards the tip of the bolt).
If you put a plate on it and apply a shock with a hammer, etc.,
The screw part at the back end (right end in FIG. 2) of the female screw 3 hits the inside end of the male screw 5, and the biting parts of the screws are crushed together, so that the nut 1 is subsequently tightened by the screw. It is impossible to leave 1.
