Zusammenfassung:	A flanged hexagon head bolt can fasten the bolt by a stable fastening axial force, and can stop rotating the fastened bolt. When the bolt is fastened, a flat bearing face of a circular disk shape flange is brought into face contact with a flat bearing face of a flange portion. Up to the stage, the flanged hexagon head bolt is the same as a bolt which does not have recessed and protruded portions, a variation in a fastening torque is small, and a fastening axial force of the bolt is stabilized. When the bolt is further fastened, the bearing face of the flange portion is inclined, and the recessed and protruded portions of the circular disk shape flange bite an inclined root portion of the bearing face of the flange portion.
