What diameter is 0BA?
6 mm diameter
The sizes were actually defined in metric terms, an 0BA thread having a 6 mm diameter and 1 mm pitch. Other threads in the BA series are related to 0BA in a geometric series with the common factors 0.9 and 1.2. For example, a 4BA thread has pitch 0.65mm and diameter 3.62mm.

What diameter is an M4 screw?
4 millimetres
They’re made from a durable carbon steel and come with a nut for tightening metal surfaces together. The M4 machine screw has a thread diameter of 4 millimetres, in simple terms the M stands for millimetres followed by the size – in this case 4 mm.
Are BSW and unc the same?
UNC and BSW have the same thread per inch value, accept for the 1/2″ size. Theoretical it would be possible to interchange them as they have the same amount of threads per inch. However due to the difference in thread angle, the connection would not be as strong as when using the proper combinations.
Is BA a metric?
British Association (BA) This is a metric thread system devised by the British for small screws used in components like speedos. Not metric like you might expect, but with diameters determined by a factor proportional to a power of the logarithm to the base 10 of the thread pitch in millimeters.

Will a UNC nut fit a BSW bolt?
So they don’t fit. UNC and BSW have the same thread per inch value, accept for the 1/2″ size. Theoretical it would be possible to interchange them as they have the same amount of threads per inch. However due to the difference in thread angle, the connection would not be as strong as when using the proper combinations.
