gasket creep and thermal expansion; many bolted joints include a thin, soft gasket between the bolt head and the joint surface to seal the joint from leakage of gas or liquid. The washer itself also acts as a spring, rebounding under the pressure of the bolt and the engagement surface; over time, especially near high temperatures or corrosive chemicals, the gasket may "creep", meaning that it loses elasticity, resulting in a loss of clamping force;
impact; the larger impact load exceeds the friction force when the bolt is pre-tightened, so that sliding is generated; dynamic or alternating loads from machinery, generators, wind turbines, etc.; even impacts tend not to take into account such large loads when designing joint connections;
when the bolt component is used on structural members with vibration generated by bodies such as rail motor cars, processing machine tools and vehicles, after the bolt component is used for a long time or after the nut is locked on the fastened piece, the fastened piece generates mechanical vibration for a long time, so that the impact force applied to the bolt or the joint by mechanical impact can cause the bolt to slide relatively; just like vibration, this sliding can cause loosening of the bolt, which in turn can lead to reduced use and safety of the fastened body.
