Where can I find a LH 10-40 UNS tap?

[acadian8]

Yes that's right, a left-hand 10-40. Tapping a through hole in 303 SS, .375 thick. Everyone is telling me it's not a standard tap size (no kidding?), but I can't find anyone who carries them. I have two of these taps but getting through 600 pieces might be dicey. Any idea where to pick up a couple more?

Victor stocks the 10-48 or 10-40 RH tap for $9.50 and they say, "In addition to the many sizes we list, custom taps to your specifications can often be shipped in as little as 24 hours."

No problem, my reply still applies. There are other makers of special taps, of course, like Widell and Regal, but Victor may be easier to communicate with. If you are not in a hurry, try them all for a quote.
