Hi Jacques, You're right! I knew it was slightly larger than a #4-40 but didn't realize they were quite that large (I didn't actually measure them but I should have).
I have an 8-36 tap that I must've bought 20 years ago when I was working on some R390As. I just wanted to clean up the threads a bit so I'm good to go now.
