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 UN, UNR, and UNJ thread forms. The metric translation of this Standard that was in the 2003 edition has been removed (see Nonmandatory Appendix C). Nonmandatory Appendices D through F contain information that is supplementary to the ections of this Standard. 本标准规定了统一螺纹的螺纹形式、系列、等级、余量、公差和型号。（为了强调统一螺纹是基于英制模块的，它们可能表示为统一英制螺纹。已经为统一螺纹开发了几种螺纹形式的变体;但是，本标准仅涵盖UN，UNR和UNJ螺纹形式。 2003年版中本标准的公制翻译已被删除（见非强制性附录C）。非强制性附录D至F包含补充本标准的信息。
