... This article discusses the effect of thread design, preload, tightening, and mean stress on the fatigue strength of bolt steel. It describes the factors influencing fatigue failures in cold-driven and hot-driven riveted joints. The factors affecting the fatigue resistance of bolted friction joints are also...

... or eliminate fretting fatigue. For amplitude-controlled fretting, the opposite effect can be expected and a reduction in the coefficient of friction is desired since the surface shear stresses are reduced. Reduction in coefficient of friction for clamped (bolted or riveted) joints has been shown...
