Generally, a hexagonal wrench is a bolt having a hexagonal groove formed in the head of the bolt, and the bolt is rotated using a hexagonal wrench to be fastened or detached with a nut or the like.

There is a problem in that various devices using such a hexagonal wrench bolt can easily loosen the bolt if it has only one small wrench.

Therefore, there is a need for a bolt with a safety device to prevent the hexagonal wrench bolt from being easily released using a wrench even if it is not a complete safety device.

As a conventional technique, a bolt of a safety structure formed by a driver capable of forming a protrusion having a specific shape in a bolt head screw groove and using only the bolt is known in Japanese Patent Application Laid-Open No. 10-2010-0053767.

The present invention relates to a hexagonal slotted bolt with a locking device. When a key is inserted into a hexagonal slot and then the key is inserted and rotated, the stopper is prevented from being caught in the hexagonal slot, This prevents a person other than the user from using a conventional hexagon wrench to unscrew the bolt. Further, in order to prevent the bolt head from being caught, the present invention is formed into a cylindrical shape whose outer diameter becomes smaller toward the end of the bolt head, and is formed so as to be difficult to be picked up by a clamp or the like.

In the present invention, when a key is rotated by inserting a lock into a hexagonal groove of a tightened hexagon wrench bolt, the stopper is protruded to be inserted into a groove formed in the inner wall of the hexagonal groove so that the lock does not come off. And it is an object of the present invention to provide a bolt provided with a locking device formed so as to prevent the bolt from being loosened.

In order to achieve this object, the present invention is characterized in that two grooves (113, 114) are formed so as to face a lower wall surface in a hexagonal groove (111) of a bolt head (110-1) Is formed with a hexagonal wrench bolt 110 having an outer diameter smaller toward the end of the bolt head 110-1;
