The present invention relates to an expandable high strength bolt assembly. The subject innovation is the high-strength bolt 20 is inserted into the fastening hole 15 having a diameter exceeding 2mm in the diameter of the high-strength bolt 20, the washer 23 is increased in diameter in accordance with the increase ratio of the fastening hole (15) ) And nut 25. According to the present invention configured as described above, it is possible to increase the size of the fastening hole without reducing the frictional force by the high-strength bolt assembly, which facilitates the workability, and can cope with the changing of the construction conditions resulting from inconsistency between the factory production and the site situation. There is an advantage.
