abstract

This paper presents an experimental investigation of the effect of thread root non-conformance on the fatigue performance of preloaded M12×1.5 Class 10.9 fasteners. Thread roots were dimensionally inspected using optical methods in accordance with the DIN 933 specification. Axial load fatigue tests were performed in accordance with ISO 3800. Each bolt specimen was subjected to a fixed stress amplitude of 42 MPa above and below various levels of the mean tensile stress. Test data was analyzed and fracture surfaces were examined using a Scanning Electron Microscope (SEM). Analysis of the test data showed that a non-conforming thread root radius had an adverse effect on the fatigue performance of preloaded threaded fasteners.
