The screws on a friend's closet door are stripped. The screws are #9 hinge screws. The only longer screws I had were #8 x 2. They didn't work. I know the trick about inserting match sticks and glue, but is there another (or better) way to put wood back in the hole? I have some #9 x 2-1/2" screws, but I want to make sure they're biting into solid material.
