International Standards is normally carried out through ISO technical committees Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters o f electrotechnical standardization The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part In particular the different approval criteria needed for the di fferent types o f ISO documents should be noted This document was dra fted in accordance with the editorial rules of the ISO/IEC Directives, Part (see www.iso org/directives) Attention is drawn to the possibility that some o f the elements o f this document may be the subject o f patent rights ISO shall not be held responsible for identi fying any or all such patent rights Details o f any patent rights identified during the development o f the document will be in the Introduction and/or on the ISO list

STANDARD ISO 529:2017(E) Short machine taps and hand taps Scope This document specifies the general dimensions o f 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 This document 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 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 Annex B gives an abstract from ISO 237 for shank diameters and size of driving squares, for information NOTE Technical specifications for taps covered by this document (including marking) are given in ISO 8830 Normative references The following documents are re ferred to in the text in such a way that some or all o f their content constitutes requirements o f this document For dated re ferences, only the edition cited applies For undated re ferences, the
