    1"-10 double lead thread

    we are macining a 1"-10 double lead thread. What is the proper way to measure that thread using a thread pitch mic? Would you use the standard thread pitch tolerance from the machinery hand book for a 1"-10 thread?

    Busch = you would have 20 tpi. So use a measurement for 20 threads. If you measure for 10 tpi there would be no space left for the second lead.
