The invention discloses a bolt component anti-loose method. The bolt component anti-loose method comprises the steps that a groove is formed in the thread part of a bolt; an anaerobic adhesive with solid state in an initial state is injected into the groove; in the screwing process of the bolt, thread engagement is started, the anaerobic adhesive is heated through extrusion of thread engagement, the anaerobic adhesive is converted into liquid, and the anaerobic adhesive enters a gap through thread engagement; and after the bolt is tightened in place, the anaerobic adhesive is cooled and finally converted into a solid state. According to the bolt component anti-loose method, a rubber anti-loose element is added, the solid anaerobic glue can be heated and converted into liquid state due to extrusion of the threaded engagement in the screwing process of the bolt, and the liquid anaerobic glue can enter the gap through the thread engagement, that is, enter the interior of an engagement system; and after the bolt is screwed in place, the anaerobic glue is cooled and finally converted into the solid state, the solid anaerobic glue can improve the firmness of thread engagement, and the bolt looseness and disengagement are effectively avoided, so that the fastening connection performance is improved.
