Was going to buy a few of these thread checkers for the guys at work, then I noticed the thread selection offered. 1-12 for the 1" NF selection when it should be 14 , 7/8 apparently doesn't exist and the metric set doesn't include 18mm.

I can buy them and make the missing gauges, but what a shame.
