Fractographic analysis showed that the Tee-nut has failed by fatigue. The fatigue crack was found to have initiated at the root of the threads on the inner diameter of the nut. No metallurgical and/or mechanical abnormalities were responsible for the fatigue crack initiation. Since the component was in service for about 25 years, the Tee-nut appears to have served its intended life. The nut was made of cast high leaded brass (Ounce metal) equivalent to BS1400 LG2 specification.
