This is aired elsewhere on this forum some time ago and I think the reason concerned wrongly made studs made in quite a large batch that escaped with nuts to match
Sorry to be vague I will search when I have time or perhaps someone else will

Is this the thread your thinking of? Ernie asked for someone to measure the thread profile of a stud.

Thanks for your reply. IF worn the nut would rattle around on the stud but could still fit.

Regards Alan.
