A:Answer Update on Samsung 65" 8000 series. The bolts supplied aren't quite long enough. I ended up finding the longer bolts needed to work with the spacers that came with the TV. The spacers that come with the TV work much better than the ones supplied with the mount. The bolts that I found to work best were size M8-1.25 by 50 mm long. I was able to find these (metric) bolts at Lowes, in a small bag of 4, for about $2. I used the spacers that came with the TV, the 4 (50mm long)bolts, 4 flat washers (in mount hardware), and 4 split lock washers (also from Lowes). TV is mounted securely and mount functions as described.
