    DWM,
    That doesn't look quite right there, where did you buy the bolt from, its almost cast in its entirety?

    Who installed the new bolt? I presume from the result that it was not bearing properly on both lug's.
    Worth getting someone like Brian Dickicon to inspect the part's of that bolt; check out the quality of the steel.

    Looks like a perfect example of Brittle fracture of steel to me.

    Take it to a university metallurgy department and have them analysis the steel. They'll probably be glad of the practice.
