The big thing is making sure that you have to top part level. I just eyeball it. Tighten on side, then tighten the other. You can tighten them pretty good with a normal allen wrench. I use locktite to make sure it doesn't come undone. The concern is bending the scope tube, but that takes some effort to do.
Unless you are shooting long range competitions, just use judgement. That good enough for most people.
There is no such thing as a stupid question, only stupid people.
