What is the nearest American standard screw thread to 6 BA (British Association) screw thread?

 

Probably close #6-32

 

Does BA use worldwide metric sizes?

 

BA 'British Association' thread was used extensively in the UK at one point, initially for small projects such as modelling etc.
I am assuming that most of UK has gone metric now.

 

6 BA is 2.8mm outer diameter, so i think it would be #4 .

 

Is BA thread commonly used anymore now for new UK equipment?

Not seen BA threads since the 70's,
whitworth et all have gone, ( thank goodness )

even the metal box's in the wall that the power sockets screw into went metric,
but I have a few old BA threads for repairs of old sockets in my grandmas house.

Not really, it's mainly used in old radios and TVs, we've gone metric now, but you can still buy BA nuts and bolts on the internet.

I still have my old BA taps and spanners, not really much use in Canada !!
