OH crap, I just put away my tap and die sets. I usually do not do put away very well. I found on the computer, a "BSC" (British Standard Cycle) that shows a 9/16" (0.5625" x 26 TPI) I'm still looking for a name I can really trust to list on this mechanical drawing. when I had the thread pitch gauges out my fractional tap and die set 27 and 28 TPI were awfully close matches. I should have gotten more light and a piece of white paper as a contrasting back ground. Other than the Wentworth I have never heard of these thread systems before. Talk about living in a BOX.
