In essence, "ISO 2768 m H" specifies the general tolerances for linear and angular dimensions, as well as form and orientation deviations, for features of size (like holes, shafts, etc.) in a mechanical part or assembly, using a medium tolerance class.

In ISO 2768, "m" and "H" refer to the tolerance classes for linear dimensions.
The "m" class defines permissible deviations based on the size of the dimension. As the part gets larger, the allowed deviation also increases. Nominal Length Range (mm) Permissible Deviation (± mm) Over 3 to 6 Over 6 to 30 Over 30 to 120 Over 120 to 400 Over 400 to 1000 Over 1000 to 2000 Over 2000 to 4000 Sources: ZEISS Quality Forum , Engineers Edge ISO 2768-2: Geometrical Tolerances (Class "H") In essence, "ISO 2768 m H" specifies the
In conclusion, ISO 2768 provides a framework for specifying geometric tolerances in technical drawings. The "m" and "H" tolerance classes are commonly used in engineering and manufacturing to ensure the accuracy and interchangeability of parts. By understanding the tolerances provided in ISO 2768, engineers can design and manufacture parts that meet the required specifications and functionality.
