Dads...and Loctite (242, I think - removeable, it's blue in color). Get a small bottle at your local auto parts store. Use a toothpick to put a tiny bit on the threads of the screw so it doesn't happen again. I use it on lots of stuff where unscrewing would be problematic. Like the bolts that hold the rear carrier to my bicycle. It doesn't like plastic. Great stuff.
