[sdiy] can shipping cause nuts to cross thread??

[Dave Magnsuon]

The little nut may have no inertia - but: I've seen more than one piece of
commercial gear that uses the jack fasteners to hold the PCB in place.

I could see a hard jolt moving the PCB, thereby twisting the plastic jack,
and damaging the (presumably plastic) threads.  It would look cross
threaded, although it would be more of a shearing/tearing action

I think this whole thread amounts to:   "If a tree falls in the woods and no
one is around to hear it...."

Oh come now!  A little nut doesn't have any inertia.  Besides, it would need
to be grabbed and twisted to x-thread it.
