The engineering texts will tell you that threaded fasteners are to be
used only in tension. snip See Carroll Smith's series on
race-car engineering, particularly the fasteners and plumbing book.

What exactly does he say? Are those books the origin of this myth? You
can't ignore shear, but it's just not so that screws must never be
subject to shear. See the recent thread "Are higher grade bolts more
brittle?"
