A:Answer The required bolts normally come with the wall mounting bracket.
M6 bolts are required to mount the hanger brackets to the back of the TV, the back is flat so no spacers should be required.
Mounting the wall bracket should be done with 1/4” lag bolts at least 2” long, directly into wall studs, don’t forget to pre drill the holes with the proper size drill, The TV weights almost 90 pounds so it must be well supported, just screws into drywall won’t be sufficient. Also make sure to have at least 2 strong people to mount it on the wall, 3 would be better!
