ISO 2ba taps

[Kenny G]

I have a need for a 2ba set of taps, Tapered, second , and bottoming. I have actually ordered a set from ebay but it,s going to take a month to get them and if someone here has a set they would like to sell PM me. I need them for threading dart barrels I have no idea why they don't just use a metric thread. The majority of replaceable tips and shafts are 2ba.

Not that it helps you any, but the BA (British Association) threads are a metric-based thread. They just aren't ISO Metric because those other people set up that standard. 2BA has a major diameter of M 4.70 and a pitch of M 0.81.

@wa5cab thanks I suspected they were a obscure metric and I did find a US supplier a branch of British Fasteners so all is well.

OK. Good deal.
