Disclosed is a method for assembling a mounting nut for a sub frame. According to an embodiment of the present invention, the method for assembling the mounting nut for the sub frame is to assemble the mounting nut for coupling the sub frame and a front side member of a vehicle to the front side member. Support portions protruding in a radial direction are integrally formed at the center of the mounting nut and through holes are formed on one lower surface of the front side member. A left surface having grooves is formed on the inner surface corresponding to the through holes. The lower part of the mounting nut is inserted into the through hole so that the support portion is supported to the circumference of the through hole. A head part of the mounting nut is mounted on the left surface, the support portion and the head part are respectively welded and assembled along the circumference of the through hole and the side part of the left surface.
