Describes the general dimensions of short machine taps and hand taps.

This document 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. This document is applicable to taps intended for cutting the following threads: ISO metric threads: coarse pitch; fine pitch; ISO inch threads: “Unified Coarse?? series (UNC) and “Unified Fine?? series (UNF); Inch threads, non-recommended: “British Standard Whitworth?? (BSW) and “British Standard Fine?? (BSF); “British Association?? (BA). NOTE1 The overall length, thread length and diameters of shank for taps whose thread diameter and pitch are not listed in tables are given in TableA.1a. NOTE2 AnnexB gives an abstract from ISO237 for shank diameters and size of driving squares, for information. NOTE3 Technical specifications for taps covered by this document (including marking) are given in ISO8830 .
