I am just getting ready to put a tv mount in the living room, above the stereo. My question is the length of screws. I have some lag bolts that say they are 1.5"... when inserted through the mounting bracket, they stick out appr 1 1/8"... is this too long? Kind of just eyeballing the wall thickness. I might add a washer on the mount side, to give me about 1" of screw going in to the wall.
Or should I get a shorter lag bolt/screw... they had 1" at the hardware store, But that wouldn't leave much biting into the wall. Maybe I need to try a different hardware store, find a 1 1/4".
