Are "any" machine screws OK to secure a TV to the mount?
You can use any machine screw of the appropriate length and diameter. Caution: If the screw wobbles significantly in the hole then the screw is really too small and can pull apart, perhaps the screw is metric and the hole is English or vice versa.
Look closely at the threaded holes in the back of the TV where the mounting screws will go. You can see, or you can probe using a toothpick to figure out, the depth of the threaded portion and also the total depth.
The screw only has to go in 3/8 inch (or slightly more than the depth of the threaded area if less) to get a good hold on the TV. If the screw is longer, all you need to do is make sure that the screw does not bottom out in the hole. A screw that bottoms out can crush electronic parts inside.
