This International Standard applicable to threading taps, for the manufacture of ISO threads, contains the most important shapes of these, as well as their measurements. Indicates equivalent terms in the three official ISO languages. This International Standard should serve as a guide for users and manufacturers. However, the graphs shown serve only to clarify this terminology, since the execution of threading taps may vary depending on the respective manufacturer. This International Standard contains:
——designations of the most important shapes of threading taps (see chapter 3);
——characteristics of the cutting pieces (chapter 4);
——thread tapping set (chapter 5);
——dimensional characteristics of threading taps (chapter 6);
——thread profile of the threading taps (chapter 7). In addition, numerical symbols are added for certain designations in order to identify dimensional characteristics.
