I went to home depo and went through several until finding M8-1.25 x 25MM or 8mm and 25mm. They worked perfectly and I was able to hang it. Hope this helps.
The screws that came with the mounting kit are not the correct size and length for the back of the new TV. Screws did not come with the unit. The users manual does not identify the size. Where can I find the screw size for this item. Thanks in advance.
