ISO 529:2017规定了短机器丝锥和手动丝锥的一般尺寸。这些尺寸是螺纹直径和螺距的函数,如下所示:
-螺纹长度(最大);
-总长度;
-驱动方的柄直径和尺寸;
-柄部和螺纹部件之间的连接部分的尺寸。
ISO 529:2017适用于用于切割以下螺纹的丝锥:
a)ISO公制螺纹:
-粗节距;
-精细间距;
b)ISO英制螺纹:
-“统一粗”系列(UNC)和“统一细”系列(UNF);
c)英制螺纹,不推荐:
-“British Standard Whitworth”(BSW)及“British Standard Fine”(BSF);
-“英国协会”(BA)。
注1螺纹直径和螺距未列于表中的丝锥的总长度、螺纹长度和柄直径见表A。1.
注2附录B给出了ISO 237刀柄直径和驱动方尺寸的摘要,以供参考。
注3本文件涵盖的水龙头技术规格(包括标记)见ISO 8830。
ISO 529:2017 specifies the general dimensions of short machine taps and hand taps. These dimensions, established as functions of the thread diameter and pitch, are the following:
- length of thread (maximum);
- overall length;
- shank diameter and dimensions of driving square;
- dimensions of the connecting portion between the shank and threaded part.
ISO 529:2017 is applicable to taps intended for cutting the following threads:
a) ISO metric threads:
- coarse pitch;
- fine pitch;
b) ISO inch threads:
- "Unified Coarse" series (UNC) and "Unified Fine" series (UNF);
c) Inch threads, non-recommended:
- "British Standard Whitworth" (BSW) and "British Standard Fine" (BSF);
- "British Association" (BA).
NOTE 1 The overall length, thread length and diameters of shank for taps whose thread diameter and pitch are not listed in tables are given in Table A.1.
NOTE 2 Annex B gives an abstract from ISO 237 for shank diameters and size of driving squares, for information.
NOTE 3 Technical specifications for taps covered by this document (including marking) are given in ISO 8830.
