The fatigue strength is one of the important quality characteristics of bolts, and how to carry out the quality assurance for this characteristic is one of the problems facing users and suppliers of bolts. The present status on the standardization of the fatigue testing of bolts is mentioned and the concept of the basic values for the fatigue limits of bolts is presented. Based on the above-mentioned basic values for the fatigue limits, a method of fatigue testing of bolts for quality assurance is proposed. In this case the required number of test specimens is 4. As the specimens, the bolts of M10-8.8 are prepared. The 14 S-N method (the required number of test specimens is 14 at least) and the proposed method are applied to such specimens. With regard to the mean values of fatigue limits, a significant difference is not found between the results obtained by the two methods.
