BA is British Association. I think 2BA and 4BA are the most common sizes
we might see. UNC is Unified Coarse which is almost, but not quite, the
same as ANC. BA is not Whitworth.

If your
screws aren't 6x32's already, the easiest and probably most practical
thing to do is get a 6x32 roll-tap, and "fix" the application so you can get
the "right" screws whenever you need.
Fine in the States, but have you tried getting 6-32 screws (or any small
UNC screws) over in the UK? They are essentially unobtainable. ISO metric
(M3) are trivial to get, so are the strange 'BA' screws (strange because
of the 47.5 degree thread angle foe one thing!).
