Product Code:SAE AS8879
Title:Screw Threads - UNJ Profile, Inch
Issuing Committee:E-25 General Standards For Aerospace And Propulsion Systems
Scope: This SAE Aerospace Standard (AS) specifies the characteristics of the UNJ profile inch series of screw threads, to include a mandatory controlled radius of 0.18042P to 0.15011P at the root of the external thread and with the minor diameter of both external and internal threads increased to provide a basic thread height of 0.5625H in order to accommodate the external thread maximum root radius. The following detailed requirements are included: a. UNJ basic profile and design profiles; b. standard series of diameter-pitch combinations for nomral thread diameters from .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. inspection and verification requirements; g. tables for selected diameter-pitch combinations for aerospace screws, bolts, nuts, shaft and bearing retaining screw threads, fluid fittings, and other component thread sizes; h. tables for UNJ screw threads limiting dimensions and tolerances; and i. symbols for UNJ thread dimensions and tolerances.
