Automatic guide fastening assembly

The utility model relates to an automatic guide nut which comprises a nut body, a normal thread section I and an unthreaded hole guide section are arranged on a screw hole of the nut body, one end of the screw hole of the nut body is the normal thread section I with threads, and the other end of the screw hole of the nut body is the unthreaded hole guide section without threads. Through the unthreaded hole guide section, the nut can be conveniently sleeved on the bolt in a normal position, and the situation that in the prior art, inclination is easy to occur when the nut is sleeved at the beginning is avoided. And the situation that threads are damaged due to inclination in the bolt tightening process is avoided. 本实用新型涉及一种自动导正螺母，包括螺母本体，螺母本体的螺孔上设有正常螺纹段Ⅰ和光孔导向段，螺母本体的螺孔一端为设有螺纹的正常螺纹段Ⅰ，螺母本体的螺孔另一端为未设有螺纹的光孔导向段。通过光孔导向段能方便将螺母正位的套在螺栓上，避免了现有技术中一开始套螺母时就容易出现倾斜的情况。避免螺栓拧紧过程因倾斜而导致螺纹损坏的情况。
