标准范围

本国际标准规定了英制UNJ系列螺纹的一般要求和极限尺寸航空航天结构的受控根部半径。它确定了这类螺纹的基本三角形轮廓，并给出了指定直径和长度的系统每英寸组合的螺纹数。对于所有直径为0060英寸（1524毫米）至6000英寸（152.4毫米）的产品，它提供表格的形式包括直径和每英寸螺纹数选择的基本尺寸和公差组合。它还提供了任何直径和直径的尺寸和公差的计算方法表中未给出每英寸组合的螺纹数，包括直径超过6000英寸。

This International Standard specifies the general requirements and limit dimensions of inch series UNJ threads withcontrolled root radius for aerospace construction.It determines the basic triangular profile for this type of thread and gives a system for designating the diameter andnumber of threads per inch combinations. For all diameters 0,060 in (1,524 mm) to 6,000 in (152,4 mm), it offers inthe form of tables the basic dimensions and tolerances for a selection of diameter and number of threads per inchcombinations. It also provides the method of calculation for the dimensions and tolerances for any diameter andnumber of threads per inch combination not given in the tables, including threads with a diameter in excess of6,000 in.
