Hi all - does anyone know the thread class of fit for BP leadscrews? I searched a bit and have found dimensions of 1 1/4 x 5 acme, but no reference to thread class 2C, 2G or other.

I’m doing another project altogether which will require some 2C centralizing acme nuts, and the bridgeport nuts are readily available. Thanks!
 
IIRC, most lead/feed screws, at least for older equipment, were for the most part centralizing. Also, I somewhat doubt that BP uses a class 2 thread fit.

How many do you need?
