What size screws are required to mount a 37 inch Vizio LCD?

I used 6m bolts and washers with measurements of 20.00 length and .1 Screw point. I bought them at Lowes for less then $5.00 and they worked great for my TV. However, I have a Sumsung but I was told that the brand does not matter as much as the size of the TV. Hope this helps.
