机用短丝锥和手用丝锥

[中文适用范围]： 本文件规定了短机用丝锥和手用丝锥的一般尺寸。这些尺寸是根据螺纹直径和螺距确定的：- 螺纹长度（最大）；- 总长度；- 柄部直径和驱动方尺寸；- 柄部和螺纹部分之间的连接部分的尺寸。 本文件适用于用于加工以下螺纹的丝锥：a) ISO 公制螺纹：粗牙螺纹；细牙螺纹；b) ISO 英制螺纹：统一粗牙系列（UNC）和统一细牙系列（UNF）；c) 英制螺纹，非推荐使用：- 英国标准惠氏螺纹（BSW）和英国标准细螺纹（BSF）；- 英国协会（BA）。 [外文原描述]： 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.
