This is *not* the same "everyone knows it" trick about backing out a
screw to find the thread.
Thanks for clarifying! Sorry about the assumption.
I still see them as closely related variants of the same technique - you
are backing out the screw to find the residual remains of the threads.
In automotive work, the competent OR EXPERIENCED wrench knows the
difference between "cutting" v "rethreading"/"restoring"
taps and dies,
for the same reason.
I do know some people who are constantly sharing "great new tips" that
they have just learned, that are usually things that it is hard for me to
imagine anybody not knowing - such as "start the lugnut a few turns onto
the stud before using the power wrench", or "make a small pit or starter
hole before drilling the full size hole", or "don't tighten any of the
bolts all of the way until they are ALL snug". There are some otherwise
sentient people who manage to reach adulthood before learning such things.
Wonko the sane would find that amusing, along with the "wear safety
goggles" boilerplate on the package of a Harbor Freight hose nozzle.
