How much weight can you mount to a wall?
I've only recently moved beyond yellow wall plugs and into a different style of self taping plug that's rated to significantly higher weights. These plugs advertise 80 lbs of pull out / 120 lbs of down ward pull through.
What kind of weight can the dry wall withstand before it fails? I'm looking at regular household application, so standard width sheets apply (since I'm sure the width will affect this answer).
I sort of wondered this on the metal, butterfly style plugs but at least they seemed to distribute the load on a larger section of the drywall.
In response to some of the questions, assume 16" on center, say 1/2" or 5/8" sheets. My specific application is hanging shelving (screw down strip/track, 5 screws per strip about 12-18" each apart, strips mounted 30" apart, lock in 8" hanger style arms) which I have done many times before. I'm not looking to push the envelope on how much I can get away with, I'm trying to ascertain whether the drywall would fail before the plugs would, for a better practical knowledge.
