Ultrahigh-strength screw with high yield limit ratio

The utility model provides a screw with high yield ratio and ultrahigh strength, which comprises a screw with high yield ratio and high strength, and is characterized in that the screw with high yield ratio and high strength is mainly composed of two main structures, namely a screw bolt structure and a screw nut structure, and the screw bolt structure and the screw nut structure are both special bolts and nuts. The screw bolt structure is a stud made of internal threads, and the screw nut structure is a nut made in a semi-wrapping mode. The overall structure of the high-yield-ratio and high-strength screw is connected in an internal connection wrapping installation mode, the threads of the structure are not formed in the surface position of the stud of the screw, and by means of the mode, when vibration or external force is applied to the stud, the threads can be prevented from being damaged. The phenomenon that the stud is broken or torn due to a thread notch is reduced, a notch is not provided for tearing f
