I am a new home owner and was looking to mount my 65” TV to a wall. The total weight of the TV with the TV Mount is 50lbs. I used a Stud Finder and determined due to the stud placement, I would be unable to centre the TV correctly. The studs are 24 cm apart but to have the TV centred, I would need to cover 48 cm across to another different stud.
As a result, I was looking to use 3/4” OSB that is approximately 52” wide by 13.5”. I purchased #10x2.5” Wood Screws that I would be drilling through the OSB, drywall, and into the studs. Due to the width of the OSB, I was going to drill into 3 studs with 3 screws each for a total of 9. First off, will this be secure enough or should I use another material than OSB or different screws.
Lastly, I will be mounting the TV Mount to the OSB with the provided four 50mm Lag Bolts. I know these will go through the OSB and then into my drywall too. Would you recommend I get a shorter Lag Bolt? Or will this whole configuration be secure?
Appreciate any and all help!
