Abstract
A method of manufacturing a member for fastening by joining a nut with a tubular joint portion extending from a main body formed with an internal thread to a panel with a mounting hole for the nut on an aluminum base material. The joint portion has a rotation-preventing portion with a concave and convex shaped outer peripheral surface and a guide portion extending from the rotation-preventing portion to one side. After the guide portion is inserted into the mounting hole, the nut is energized by electrodes in contact with both nut end surface sides. The nut then generates heat, and the periphery of the mounting hole is heated and softened. When the nut is pressurized with the electrodes, the rotation-preventing portion bites into the mounting hole, and the one end portion of the guide portion is swaged to become a retaining portion on one surface side of the panel.
