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.
