This paper is a study on fatigue life evaluation of high strength bolt. The effect of axial loading result from torque on the fatigue life of bolts has been investigated. It was found that the fatigue limit of bolts increased by an amount proportional to the increase in torque. there was linear relationship between torque and fatigue limit. Using the method of Shigley, the prediction of fatigue limit from calculated stress concentration factors was also examined. A good correlation was found between the experimental and predicted fatigue limit. The method of Shigley was appropriate for evaluation of fatigue life to bolts.
