適用范圍

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. 本標準規定了統一螺紋的螺紋形式、系列、等級、余量、公差和型號。（為了強調統一螺紋是基于英制模塊的，它們可能表示為統一英制螺紋。已經為統一螺紋開發了幾種螺紋形式的變體;但是，本標準僅涵蓋UN，UNR和UNJ螺紋形式。 2003年版中本標準的公制翻譯已被刪除（見非強制性附錄C）。非強制性附錄D至F包含補充本標準的信息。
