| Abstract: | The concepts of threaded bolts torque coefficient were presented, the experimental research status of influence factors that determine the torque-tension relationship and its application were reviewed. The frictions of thread and supporting plane determine the torque coefficient. The purposes of the research lies in to lower torque coefficient and improve its stability. The environmental temperature and humidity should be more considered for the significant outdoor high strength bolts connection sites. |
