I would not venture to take a guess.

However if I were motivated to use only 3 holes I would purchase longer screws in stainless steel. The stainless steel part is important. It approximately doubles the tensile strength.

I work construction. Stainless steel screws are terrible. They snap, bend, and the heads strip far more easily than normal steel. The only use for them is if you really need to avoid corrosion.

I'll just get drywall mud and redo it again with a Ryobi driver/impact set. Any suggestions for drill bit brands?
