If you've always had the stealer change your oil, then they are the only ones who touch the screw and the only ones that could have striped it!! wouldn't you think? A screw doesn't strip by itself !! the only other thing is it came like this from the factroy! Either way, the Stealer needs to eat the cost IMO ...
