The utility model relates to a fatigue resistant torsional shear type fastener in the technical field of fasteners. The fatigue resistant torsional shear type fastener comprises a screw, the right end of the screw is provided with threads, the outer surface of the screw is sleeved with a gasket, the outer surface of the screw is in threaded connection with a nut, the right side of the screw is provided with an anti-loosening mechanism, and the right side of the anti-loosening mechanism is fixedly connected with an auxiliary mechanism. By arranging the anti-loosening mechanism, in the using process, the nut is limited under the action of the limiting rod and the limiting hole, the limited nut cannot rotate, and therefore the phenomenon that connection of the fastener is loosened due to loosening of the nut is prevented, the stability of the fastener after connection is improved, and the service life of the fastener is prolonged by improving the stability of the fastener after connection. Therefore, the anti-fa
