Gents,
Recently got a big bag of about 40 asst'd taps thrown in as a "boot" on a deal for some other machinist's tools. Sorting through them, I found some oddities: 1/4-32, 5/16-32, and 3/8-32. All are marked "NS", meaning that the threads have the National Standard form.
Machinery's Handbook lists these sizes, but of course they are not NC or NF. I don't think they are NEF, either, at least not all of them.
What sort of work are they used for?
There were two other oddballs in the bag - an NPS and a "lefty". All-in-all, a nice addition to my little drawer of "Taps I'll probably never use, but which might be very useful if I ever need them"
