The bolt of M10×1.25mm×(45~8.8)mm are fractured when they were assembled. The analysis of these bolts were made by means of macro-morphology inspection, chemical composition analysis, micro-structure examination, mechanical property testing. It is shown that the microstructure of the bolts were abnormal resulted from improper heat treament which led to the descent of hardness and strength of these bolts.
