If that is your only real concern, the screws shouldn't "wear out" for a couple times per year use. Just don't over-tighten and strip them out. they only need to be snug.
There is a method which almost guarantees that the existing thread in the wood or plastic is re-engaged. Place the screw into the hole. Before trying to tighten it in, turn it slowly backwards like you are removing it. You should feel a slight bump which is the threads falling into place in the old grooves. Stop and then turn the screw in to tighten it. The threads of the screw should engage and pick up the old threads. That helps to keep the holes from enlarging with each use.
