I have installed hooks in the bathroom door, nailed gun in shelves in the coat closet by putting rails in the walls for the shelves to sit on, put a coat rack that is a shelf with hooks from target, and put a hooks on the walls in the bedroom and all I do is use short #8 screws with a dab of liquid nails on the screw. I don't want it to accidentally get tugged on to hard and rip a hole in the wall. Especially the bathroom door hook I added was with short screws and liquid nails on the back plate of the double hook I got from lowes. Works like a charm.
