These gages meet the following standards: American National or U.S. 60°, Whitworth or English 55°, and Metric 60°. They also have a very useful scale for finding the number of threads per inch through graduations in 14ths, 20ths, 24ths and 32nds of an inch. The gage also has a table of double depths of threads for determining size of tap drills.
