A self-locking nut comprises a slotted nut and a locking nut and is assembled by complementary asymmetrical threading. After the locking nut is threaded onto the neck of the slotted nut, the assembled self-locking nut turns freely as it is threaded onto the shaft of a bolt. Once the forward face of the slotted nut contacts the material being fastened, additional turns clamp the material to the desired torque. Now, when additional torque is applied to the locking nut, its internal thread slides forward along the shallow incline of the asymmetrical external thread on the neck of the slotted nut, thereby exerting a compressive radial force on the slotted neck.The compressive radial force contracts the slots of the slotted nut, thus constricting the circumference of the slotted nut around the bolt shaft. As the slotted nut constricts, the female crests of its internal threads are forced more tightly against the male crests of the external threads of the bolt shaft, thereby locking the female threads of the slotted neck to the male threads of the bolt. This produces a strong 360-degree mechanical metal-to-metal connection, and does not damage or deform the threads of the bolt.
