As stated in some of the other posts, you may try a jewlers set of screwdrivers, the thing is, each of these sets is different from store to store, a #00 at wal mart may differ from a #00 at target. I recommend the eyeglasses set. after trying three different jewlers sets, i finally found the right size in a eyeglass set. And if you think the screw is frozen, keep bearing down once the loosen up you are golden.
