    OK, how about 1/2-20?

    I read last night that tapered threads are measured in the middle
    of the taper to arrive at the nominal size, and of course, pipe sizes
    go by the ID of the pipe.
    Just got home, so will look in the Machinist Handbook, but yeah,
    1/2″ x 20 would be closer perhaps.

    Prepare to be boarded!
