Anotation

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.
