Guys, I'm having a big problem with mounting screws. I'm creating my own custom mounting method for the TV. You know how if you use the stock stand, there will be 4 other screw holes that are 400mm apart vertically and horizontally? I used that to assume it was VESA 400x400 and later confirmed this after some research.
According to this page from Samsung, the VESA 400x400 uses M8 & the depth is 15mm.
I tried screwing in threading that was M8 and 15mm long, but the hole was much too narrow to fit and it didn't look that deep; this is to much frustration because I bought 4 threaded parts to connect to it, since assuming the research had concluded it would fit. The shipping cost more than the parts all together!
I just want to know what thread will perfectly fill these holes:
M = Screw size
L = Depth
