This Standard specifies the thread form, series, class, allowance, tolerance, and designation for unified screw threads. (In order to emphasize that unified screw threads are based on inch modules, they may be denoted unified inch screw threads.) Several variations in thread form have been developed for unified threads; however, this Standard covers only [Unified] UN and UNR [external threads only] thread forms. For easy reference, a metric translation of this Standard has been incorporated as Nonmandatory Appendix C. Nonmandatory Appendices A through E contain useful information that is supplementary to the sections of this Standard. B1.15 - 1995, Unified Inch Screw Threads, UNJ Thread Form has been Incorporated into B1.1 – 2019, Unified Inch Screw Threads (UN, UNR, and UNJ Thread Forms).
