Am I correct in thinking that the screw thread sizes on the airframe are all UNF?

For #10 and larger, yes. #8 and below are coarse thread.

True, though to be explicit, 10-32, 8-32, 6-32, 4-40 are the norm, though other options exist (can't say I've ever seen them).....

8-36
6-40
(5-40)
5-44
4-48

Thank you both, that's just what I needed.
