Popis: The paper deals with the fatigue behaviour of threaded connections bonded with anaerobic threadlockers. Fatigue tests are described involving rolled M10 bolts of property class 10.9 loaded under constant amplitude at the load levels 11±10 kN and 8.8±8 kN. The number of cycles to failure consequent to treatment is significantly longer than without treatment, the ratio between the corresponding lives being about 3.5 at the higher load (11±10 kN) and about 2 at the lower load (8.8±8 kN). The reduced effect with the lower load discloses a common endurance limit. The behaviour is attributed to elimination of fretting damage by the contacting threads of the bonded connections. This interpretation suggests an important role of the mean test load and fosters further investigation.
