Metric Thread and Gauge Profile Description of products Relation of tolerance position between screw thread classes and thread gauge classes in ISO(new JIS) and old JIS standard. ■External threads and Limit gauges for external threads Basic Major Dia. of external thread 10mm *Relation between tolerance zone of external thread and that of limit gauges for external thread is shown. Class 2 *Pitch Dia. of external thread is virtual pitch Dia. *Pitch Dia. of screw ring gauge is simple pitch Dia. Pitch diameter tolerance and Major diameter tolerance of external thread Tolerance of screw ring gauge and caliper gauge Minimum wear Basic Pitch Dia. of external thread 9.026mm Example：ISO M10X1.5/6g and old JIS M10x1.5/Class2 Class 2 Basic Profile Class 2 6g Class 2 6g Max Truncation Min Truncation Min Minor Dia.
