I did use the word "MAY". I've got some that would come off with that little flathead blade that comes in most cheap fold-out pocketknives. And I've got one that would be impossible to remove with a flathead driver, it has stakes all around the hole and some actually bridging the screw and the mount. It ain't coming off short of applying more torque than the slot could take. Ivan Bayostakervich brought his "A" game to work that day.
