This does 965–1 preclude the free use, in the course of implementing the standard, of necessary details, such as symbols and sizes, type or grade designations.

In some grades, certain tolerance values for small pitches are not shown because of insufficient thread overlap or the requirement that the pitch diameter tolerance shall not exceed the frree diameter tolerance.
