Ordinary thread limit deviation
1 Scope
This document specifies the limit deviations of the pitch diameter and top diameter of ordinary threads (M): The basic tooth form and diameter and pitch series of ordinary threads are respectively
Comply with the provisions of GB/T 192 and GB/T 193, and the basic deviations and tolerances comply with the provisions of GB/T 197:
This document applies to ordinary threads using the recommended tolerance zone:
2 Normative reference documents
The contents of the following documents constitute essential provisions of this document through normative references in the text: Among them, the dated quotations
For undated referenced documents, only the version corresponding to that date applies to this document; for undated referenced documents, the latest version (including all amendments) applies to

3 Terms and definitions
The terms and definitions defined in GB/T 14791 apply to this document:
4 Limit deviation
The limit deviation values of pitch diameter and top diameter of ordinary threads should comply with the provisions of Table 1:
Any point on the actual tooth bottom contour of the internal and external threads should not exceed the maximum physical tooth form determined by the basic tooth form and basic deviation:
If there are no special instructions for coated threads, the tolerance zone applies to the threads before coating: After coating, no point on the actual thread profile should exceed
The maximum solid tooth form determined by the tolerance zone position H or h:
