I would like a second opinion on the above thread.

is ISO & ASME B1.13M the same?

Here is what I calc out.

Maj dia ~30.0-29.850mm
P.D. ~ 29.026-28.931mm
best wire~.86602 mm
MOW~30.32504-30.23004mm

Thanks in Advance

My software outputs numbers that agree with yours, +- .001mm.

ISO DIN 13 agrees with first two (Maj. dia. - Pitch dia.)
3 wire measurement is not listed.
