does anyone know what the bolt hole circle tolerance is for these type of flanges?

The bolt circle is a basic dimension. The tolerance is taken on the bolt hole location (position) relative to the theoretically perfect location, and should typically be within 0.06 on the diameter (bolt holes are oversized by about 1/8", so each flange can have that much out-of-position error and still align to each other).
