Although any size wire between the minimum wire size and the maximum wire size may be used, common practice is to use the best wire size. - NPT Thread taper angle = 1/16 taper = 1 deg. Standard thread gages are made to a Class X tolerance. Thread Gage Pitch Diameter Chart. Do not use these values for standard metric internal thread design. The designation of a screw thread gives the thread symbol, the nominal size, the pitch, and the thread tolerance class (Ex: M6 x 1 - 5H6H). \"GpUpCX)%?8s Gauge Type: Diameter Range: Pitches in mm: Tolerance Class: Thread Plug Gauges. 2.
