I've always had the question of how much weight can a single screw into a drywall withstand?
For instance, I would like to do things like this:
It's hung with 5 screws. The whole thing weighs approximately 50kg (110 pounds) so we can say that each screw holds approximately 10kg (22 pounds).
The person who installed it said it was fine, but is it really?
Do somebody know a study or some numbers regarding how much weight this material can stand?
EDIT: Just to clarify, it's not screwed to the studs. It's screwed to the drywall.
