In this study, fatigue tests of aluminum alloy bolts have been conducted to investigate the influence of clamping force of the bolted joint on fatigue characteristics. The initial clamping force was set at 2 kN, 4 kN and 6kN. The results showed that the fatigue limits decreased with an increase in clamping force. The results indicate that it was not suitable for aluminum bolts to be tightened with a higher clamping force although the steel bolt has been recommended to be tightened with a higher clamping force.
