Hello, How does one calculate the load capacity of a particular screw ?
I will be mounting my 37" plasma tv to the wall. It weighs 67 lbs. I have purchased an appropriate wall mount bracket. In a perfect world the screw holes for in the bracket would line up with the studs, but that isn't likely so I will first attach a piece of 3/4" plywood to the wall so it will span two studs. The mounting bracket will then be screwed to the plywood.
The mounting bracket will be secured to the plywood in 4 places. The TV is
67 lbs (plus the bracket itself is 12 lbs) That's about 20 lbs per screw. Will 4 screws in 3/4" plywood be strong enough?How does one calculate the load capacity of a particular screw (probably will get 1" lag screws with 1/4" diameter)?
Thanks, Rogue Petunia
