There is a spec for the flat screen and the part of the mount that
connects to it, known as VESA. This Wikipedia article gives a decent
overview:

The part of the mount that connects to the wall is left to the
manufacturer.
The original mount patterns were all square, but rectangular spacings
were added as displays got larger. I don't think M5 is part of the spec
however.

Subject: [USMA:51085] TV mounting bracket
To: "U.S. Metric Association" <[email protected]>

We have just purchased a TV wall-mounting bracket at Costco for a
flat-screen TV that we also purchased there. The bracket is made by
Simplicity. This presents a mixture of metric and non-metric
hardware dimensions and directions.
Apparently, all the fasteners that mount the TV to the mounting
bracket are metric and provision is made for four diameters (M4, M5,
M6, and M8 -- i.e., diameters given in millimeters) with lengths
ranging from 12 mm to 45 mm (not all lengths available in all four
diameters). The lag screws that mount the bracket to the wall are
non-metric: 5/16 by 2.75 in. Of course, the hole spacing on the
backs of these flat screen TVs are all metric (e.g., 100 mm, 200 mm,
400 mm, 450 mm), but here the directions give rough non-metric
equivalents (4 in, 8 in, 16 in, 18 in). The spacers (to allow
protrusion on the backs of the TVs) are 14 mm and 24 mm in depth;
one selects the needed length or none, per the TV's design.
Necessary bit sizes are given as 5.5 mm (7/32 in) and 10 mm (3/8
in). I suspect that many cheap drill bit sets do not include a 7/32
in bit. I also suspect that most Americans don't realize that size
falls between the 3/16 and 1/4 sizes they possess. That's the size
needed for mounting to studs, so there might be some dangerous
errors committed in their homes by using a terribly wrong pilot hole
size. (The 10 mm bit is for pilot holes in concrete which are then
lined with plastic inserts.)
Directions for hole depths, swing room allowances, etc. are given in
both metric and non-metric dimensions: 75 mm, 3 in; 3.72 in, 94.5 mm
in the figures; in the text, the non-metric dimensions for holes and
bit sizes are in parentheses, but for the swing allowance the metric
is in parentheses.
Directions follow the English directions in French and Spanish, but
referring back to the pictures in the English section. For the most
part the dual dimensioning practices mentioned above are still
followed -- e.g., 3 po (for pouces) and 3 pulgadas.
Language differences will persist for millenia, perhaps, but in the
meantime we could simplify our lives if everyone would use only
metric units of measure.
