Can any of the experts out there comment on the likely thread size of my Bafang hub motor please?

I bought it used without any nuts, so need to source some.

The motor has BFSWXB24V250W255R marked on it and has a 12mm O/D shaft with flats on it which bring it down to 10mm, it looks like a fine pitch thread.

I found this drawing online, which has M12 x 1.25 stated but then some of the other dimensions don't seem to tie up with my motor, so I have some doubts as to whether I should believe it!

Is M12 x 1.25 likely to be the right answer?

Thanks in advance for any advice offered.
Excellent forum this!
