You should not have to crank down hard on the set screw to tighten up the counterweight. Hold the counterweight between the thumb and forefinger, use the supplied wrench and turn until you feel resistance. The counterweight will be secure.
Even if you are applying "force" to it, if the armwand is seated properly (tungstan tip in the bearing cup of the arm), you won't bend the tip. If you do bend it, or if you have a bent one, it needs to be addressed as the arm will never track properly like that.
