Abstract

This SAE Aerospace Standard (AS) specifies the characteristics of screw threads - UNJ profile inch series, including a mandatory controlled radius as specified in Table 1 at the root of the external thread. The minor diameter of both external and internal threads provides a basic thread height of .5625H to accommodate the external thread maximum root radius. The following detailed design requirements are included: a Screw threads - UNJ basic profile and design profiles. b Standard series of diameter-pitch combinations for nominal thread diameters from 0.060 to 6.000 inches. c Standard thread classes and form tolerances. d Formulae for thread dimensions and tolerances. e Method of designating UNJ threads. f Tables for selected diameter-pitch combinations for close tolerance mechanical thread applications. g Tables for screw thread - UNJ profile thread limit dimensions.
