Standard for pitch diameter measurement
(OP)
I have following questions on measurement of pitch diameter for ASME B1.1 UNC threads.
1)Is there a standard which gives guidelines on how to
determine pitch diameter of threads by 3- wire method.
2)What is the fastest method on measuring pitch diameter
for fasteners. (I am referring to B1.1 UNC)

2) It depends. Try talking to a few industrial supply houses.

As posted above by BillPSU nothing beats the proper gages. If you purchase thread gauges please treat that as per the manufactures instructions.
If you are considering this for a production application there are numerous thread measuring stands that do a good job.
