I can't find this information anywhere on the internet and since I haven't received any replies on the various messageboards about this, I guess that I am the first person to look into this who feels the need to "spread the word". I could not find an exact match as people have been telling me but I found that a #3-48 screw is close enough to work.

I thought that I'd put this out there so that anyone else who needs to know will be able to get some screws.
