According to my chart it would take a size "D". The decimal equivalent size
is .2460. I am assuming that tap is a NPT taper pipe tap, which is where a
1/16th / 27 tap is located on my chart.

Hope this helps,

I need to make a threaded hole with a 1/16-27 thread. I have the tap, but
have looked up in the handbooks I have and cannot find the tap drill size
for this thread. Anybody know what the proper one is?
