Abstract
The utility model discloses a hexagon bolt which comprises a bolt head portion and a bolt bar. The bolt head portion and the bolt bar are integrally formed. The bolt head portion is in the shape of a regular hexagon. The hexagon bolt is characterized in that the face, away from the bolt bar, of the bolt head portion forms six bolt head chamfers on six corners of the regular hexagon. The image surrounded by the bolt head chamfers is the inscribed circle of the regular hexagon. The inside of each bolt bar is of a hollow cylindrical structure. The inside of the bolt head portion and the bolt bar forms a hollow cone-shaped structure. The hexagon bolt has the advantages that the structure is simple and a screw hole in the bolt bar provides a new manner for detaching the hexagon bolt.
