Zusammenfassung:	The utility model relates to a special nut which comprises a nut body. A threaded hole is formed in the nut body. The upper end face and the lower end face of the nut body are arch faces which are inwards concave. Anti-sliding nails are arranged on the arch faces. In the process of screwing the nut into a bolt or a screw rod, once the nut adheres to a connected part, the arch faces in contact with the surface of the connected part will deform and then generates elastic deforming force. The elastic deforming force can force the nut to be tightly pressed on the surface of the connected part. The friction between the nut and the connected part will be enlarged, thus, when the nut is subjected to strong vibration, the nut can still maintain the ideal anti-loosening performance. In addition, when the arch faces deform, the threads on the nut can cling to the threads of the bolt or the screw rod and meanwhile, the anti-sliding nails can better prevent the nut from loosening.
