I use my little impact driver on every screw I try to remove that gives me the least bit of problem with a regular screw driver. No more stripped screws ever.
This is the one I have but the one sold by Harbor Freight would be just as good/useful. Make sure you purchase some of the impact nut drivers also from Harbor Freight.
