 McMaster has T15 6-32x1/4" pan head screws for 6.22 per 100,
 which doesn't seem like a terrible price to me.  Aside from some
 visual finish, what's the advantage of a button/cheese head? 
 If you're working on a piece of older Compaq gear, the cheese head is part of the
slide-in mounting system for the disk drives.  That is, the cheese head forms the
protrusion that slides in the groove of a plastic guide. 
Ah, yes, I had forgotten about that.  I've actually removed
a few of those drives before, and have a few of those screws,
though they've mostly been repurposed.
