Up to a certain
point, I just want my screws short enough that their points
don't protrude.

YES! Especially you model railroaders out there. Please don't let that
point protude! Someone might have to maintain your work one day.

Screws are cheap and last forever if you don't use them. If you've got
space, buy 25-lb boxes of the sizes you use most and 5-lb boxes of the ones
you use less frequently. Have the right size on hand and you'll never have
to use the wrong one.
