Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents". Drafting. This document supersedes GB/T 3464.1-2007 "Machine and hand taps - Part 1.General purpose shank machine and hand taps" and GB/T 3464.3-2007 "Machine and Hand Taps - Part 3.Short Shank Machine and Hand Taps". This document is based on GB/T 3464.1- Based on.2007, it integrates the content of GB/T 3464.3-2007.Compared with GB/T 3464.1-2007, apart from structural adjustments and editorial changes... Aside from the changes, the main technical changes are as follows. a) Increased tolerances for standard thread tap dimensions (see Tables 1-6); b) A unified thread tap type and size have been added (see Chapter 5); c) Added Whitworth thread tap types and sizes (see Chapter 6); d) Added "markers" (see Chapter 7); e) Added "Thread Profile, Basic Dimensions, and Tolerances" (see Chapter 8); f) Added technical specifications for unified thread taps and Whitworth thread taps (see Chapter 9); g) Added "Detection Methods" (see Chapter 10); h) The nominal cutting angle of the tap has been removed (see 3.6 of GB/T 3464.1-2007). This document is modified to adopt ISO 529.2017 "Short taps for machine and hand use". This document has undergone the following structural adjustments compared to ISO 529.2017. ---Chapter 4 corresponds to Chapter 4 of ISO 529.2017, where 4.2 corresponds to 4.1.3 and 4.2 of ISO 529.2017; ---Chapter 5 corresponds to Chapter 5 of ISO 529.2017, where 5.2 corresponds to 5.1.3 and 5.2 of ISO 529.2017; Tables 1 and 2 correspond to Table 1 of ISO 529.2017, Tables 3 and 4 correspond to Table 2 of ISO 529.2017, and Table 5 corresponds to...
