I have walls made of OSB and plaster. What kind of screws should be used to ensure things are firmly secured? It's on a wallpapered wall, so it must absolutely not get damaged unnecessarily.
You should use wood screws that are screwed into the OSB board.
You can cut a cross in the wallpaper where the screw will go and fold up the wallpaper flaps (provided they are not too well attached). When you remove the screw, you glue and fold back the flaps.
