I did some research and found a couple of sources for flat head, 100 degrees
(not 82 as I had incorrectly stated), Torx (or 6-lobed) screws (I couldn't
find Robertson drive screws):

They sell in bulk (I think the minimum order is a full 18 wheeler) or
packages (of 100). Of course, the 100 degrees is only available in bulk.
If I already had problems storing one wing, imagine a truckload of screws.
No deal.

Microfasteners does not have a picture for this particular item, but the
description is good enough. At $9.70 for 100 (6-32 x 0.5"), I'll probably
give it a shot.
I did not try Brazos as their web site is not geared for on-line sales, so I
skipped it.
I also found an interesting discussion on Matronics, regarding the strength
of these screws. A little long, but educational. If you do a "find in page"
on "machine screw" you will be taken to one of the last postings, which sums
the whole thing up.
