To properly cut even numbered threads using the lathe thread dial indicator shown in the illustration, you should close the lathe split or half-nut on __________. Illustration GS-0084

Correct Answer: Option C — any line on the dial

When cutting even-numbered threads, the lead screw pitch is an even multiple of the thread pitch being cut. Consequently, the half-nut can be engaged at any line on the thread dial indicator because the tool will always return to the same relative position in the thread groove.
