I’ve read the original post several times and something doesn’t feel right.

Anyway, I’m an Avionics engineer and my knowledge on effects of an incorrect thread tolerance is a little limited, BUT I do work in an office with a bunch of structure geeks. So I asked them what the effects would be?

If the tolerance was too much for the "spindle" it would strip the thread when tightening(I assume your talking about the rear axel stub, spindles are on bikes). If the tolerance is acceptable then problems would only develope during the maintenance of the part (i.e. removal and re-attachment).

Take from that what you will, I personally are very suspicious of those that make claims with out giving background information.
