<p>I wondered too. So off I went on a quest.</p>
<p>Turned out to be easy. $7.99 on Amazon.</p>

– is there such a thing as a thread gauge for BA threads?
I think not as the TPI on a BA fastener is truly weird.<o:p></o:p></span></p>

having a few thread gauges, taps and dies for most BSW,
BSF, CEI, NHF, UNC, some BA and some BSPP, and a number of
references, I still occasionally get a stumper that does
not fit anything. BTW, if anyone is contemplating buying
taps and dies, I highly recommend Tracy Tools in the UK.
They sell a range of qualities, all at good prices and
provide very fast turn-around. <a

I have no personal interest in them excepting seeing good
people rewarded with business.<o:p></o:p></span></p>
