The safe service of bolts is the precondition of the full casing rotary drilling rig stable operation and high efficiency run. The operating condition is very complex and there are many influence factors. In this paper, the connecting bolts between column pressure plate and rotating support in drilling rig were taken as an example. The high strength bolts static strength and fatigue strength check analysis were expounded when subjected to axial loads or lateral loads,and relevant steps were done a more detailed introduction. Theoretical reference and technical support can be provided for the overall design of engineering structures and checking for bolt.
