Don't you want a UHF BNC adapter? Take a look at images.google.com with

Except....A UHF connector is 5/8-24 pitch.
The Amphenol button connector is 3/8-27 pitch.
Unless you consider cross threading a feature, they are not compatible.

Oh, then the 'easiest' solution I'm aware of is a pogo pin soldered in a BNC
fitting, and a lathe-job threaded tube, 3/8-27 to 38-32, to mate the threads.

I'm not sure I've ever encountered 3/8-27, but I have taps for 3/8-24./ -26. /-32
