Afaict there is no real strength or accurate placement difference as long as
more than a few threads are mating.
Okay it's going to be a lot easier to tap a 22x1.5 mm hole in 3/4" stainless
than a 22x2.5 mm hole (I tried the latter earlier, I am still sweating and
there is now a spanner apparently welded at right angles to the tap), but
are there any other advantages/disadvantages?
