Anyone know the thread on these. I had to grind the old nuts off. I suspect its bsf (looks like 22 tpi). I have a ex-military Series 2a workshop.

If they are 5/16" x 22 tpi then they are BSF.

Thanks Bigbjorn, thats what I originally thought, but the diameter is around 9.2mm, so too small for 3/8”, and too big for 5/16”.
