  • a) es is an absolute value.
  • b) (Flat form) For screw threads at maximum limits of tolerance position h, add the absolute value es to the maximum diameters required. For maximum major diameter this value is the basic thread size listed in Table 12 as Minimum Major Diameter (Dmin; for maximum pitch diameter this value is the same as listed above as Minimum Pitch Diameter (D2 min); and for maximum minor diameter this value is the same as listed in Table 12 as Minimum Minor Diameter (D1 min).
  • c) (Rounded form) This reference dimension is used in the design of tools, etc. In dimensioning external threads it is not normally specified. Generally minor diameter acceptance is based upon maximum material condition gaging.
