Awl --
I'm a big fan of coarse thread drywall screws, for mounting metal to wood
(indoors), or even deck screws, but the head is not an 82 deg c-sink, in
fact, the underside is curved.
Can I get a drywall-type thread (coarse) with an 82 deg head (or 90 deg, any
standard c-sink angle)?
Traditional sheet metal screws have a large-ish root diameter, not enough
"bite" in the threads.

They're also not as strong as wood screws because they don't have
to be.

The only question I have about these, are they soft metal like you
often see in the home centers, or are they heat treated like you find
with McFeeley's. The right heat treatment makes the screws tough but
not brittle.
Having used heat treated screws before, I hate using the run of the
mill stuff anymore.

If a drywall screw had a straight 82 (or 90) degree head it would NOT
be a drywall screw. The convex tapr on a drywall screw is to displace
the drywall topper paper without breaking it as the screw pulls in.
Break the paper and the screw isn't holding ANYTHING any more.

What is the problem with traditional wood screws?
looking at Mcmaster, drywall screw #99136A100
http://www.mcmaster.com/#cadinlnord/99136a100/=lkwr59
it is clearly the bugle head you do not want.
but part #90031A153, a No. 6#2 Phillips Drive Zinc-Plated Wood Screws
appears to be what you are looking for.

They use them all the time in production woodworking,
Go to McFeely's and look around.

Mcmaster Carr probably has something that was engineered to do whatever =
it is you are wanting to do.
