No I don't and I don't pull the stocks off my box locks to clean and oil them unless there is a real problem. I get so tired of seeing buggered screws made that way by prying owners, semi competent amateur gunsmiths and people fixing things not broken. I consider it a protected, closed system, unless I do something stupid to change it. And getting a screw out after 75 to 150 years of being in place is sometimes not easy or even possible. If not done poorly, which too often occurs, they get buggered up and for no great improvement of the gun. For the same reason I don't pull side locks to look at their design, the level of finish or see if they bear a makers mark.
Now I will strip and clean a pump or semi auto because the action is completely open to dirt and by their very nature anything that gets into them can cause problems. Also I find that they have much more need for rust prevention. I just don't see how rust can get into a well fit, set of side locks unless they have been subjected to copious amounts of water.
