Possible fixings:

and

http://www.toolstation.com/shop/p97984

To fix a TV bracket to a wood (presume veneered chipboard) panel
approximately 16mm thick.

TV bracket has 6 countersunk holes, and the metal plate is approximately 3
mm thick.

I assume the 20mm length is the thread length plus the head?

Either way, the pronged tee is inset into the wood so there will be plenty
of thread.

Looking good as long as long as the wood panel is sturdy enough.

Cheers

Should be fine in dry conditions. Possible galvanic corrosion if it was
wet, but presumably it shouldn't get wet!

Counter sunk screws always quoted as overall length. For other head
styles, lengths are measured from the underside of the head.
CSK head diameters are nominally twice the shank diameter. Other head
style sizes can vary. there are standards but makers don't always adhere
to them.

In one or two places on our boat, the hot dip galvanised deck fittings
are bolted down with stainless bolts. We haven't had any problems.

ISTR that the galvanic potential difference is small, but without
looking it up I didn't want to flag it as "OK if damp". I am pretty
confident it will be fine if dry. I should also perhaps have said not
above temperatures of 350 degrees C or so, but that seemed unnecessary
for fixings in plywood.

Stainless screws into brass screw cups on the back edge of a
stainless sink/drainer. Gets wet, no problems. OK brass rather than
just zinc but de-zincification of brass is known.
