According to the bolt fastener according to the present invention as described above, since the nut holding portion provided inside the socket of the primary fastener, which is the main part, holds the part of the outer circumferential surface of the nut, the nut can be adjusted while moving in the radial direction with respect to the center. When the nut is fastened to the bolt, the angle of the nut is distorted at the rotational center of the bolt, thereby preventing the bolt or the threaded portion of the nut from being burned out due to the angle mismatch of the nut. Strictly speaking, the nut is not twisted but is invented so that the nut moves according to the deflection angle of the bolt when the bolt inserted in the H beam is twisted. Since the bolt fastener of the present invention is mounted on the robot and the robot is always in a posture, the position of the bolt fastener and the nut fitted to the bolt fastener always maintains a constant defibrillation force.
