Go and Not Go notations
These notations conform to the "gauge symbol" of JIS standards.

Both metric screw threads and unified screw threads are manufactured in accordance with JIS standards. For a reference point: the metric screw threads have been specified to be consistent with ISO while the unified screw threads have been specified as it was before the introduction of ANSI standard.

Accuracy of SIT
The single pitch diameter tolerance, the thread pitch tolerance and the threads half angle tolerance are important in the internal thread accuracy measurement and are manufactured using the same accuracy of JIS-compliant thread plug gauges.

The screw thread precision is the same as a thread gauge, but some of the specifications like length of screw thread portion and the relief shape of the thread root are originated by YAMAWA. Therefore, these gauges are not to be called "thread gauge" and distinguished as "simple inspection tools for internal screw threads".
