The ISO 2768-MH tolerance chart is a part of the ISO 2768 standard, which was first introduced in 1989 by the International Organization for Standardization (ISO). The standard provides general tolerances for linear and angular dimensions, and it is widely used in various industries, including mechanical engineering, aerospace, and automotive.

The ISO 2768-MH tolerance chart provides a set of tables that list the tolerance values for different types of dimensions, including linear dimensions, angular dimensions, and geometric tolerances.

: Allowed deviation is 0.1 mm maximum across all sizes. Why Use ISO 2768-MH?

For angular features, permissible deviations are based on the length of the shorter side of the angle being measured. Length of the Shorter Side (mm) Permissible Deviation Up to Over Over Over Over Table 4: Geometrical Tolerances (ISO 2768-H)

ISO 2768 is an international standard aimed at simplifying technical drawings by defining general tolerances for linear and angular dimensions, as well as geometrical tolerances (straightness, flatness, etc.). It is divided into two main parts:

If you want to tailor this data for a specific project, please tell me:

| Nominal Size Range (mm) | Tolerance (± mm) | | :--- | :--- | | 0.5 up to 3 | ±0.2 | | Over 3 up to 6 | ±0.5 | | Over 6 | ±1.0 |

These general tolerances apply to angular dimensions, usually measured in degrees and minutes based on the length of the shorter side of the angle. Length of Shorter Side (mm) Tolerance Limits (Degrees/Minutes) Over 10 to 50 Over 50 to 120 Over 120 to 400 4. Straightness and Flatness (Class h - Fine)

Fixed at a maximum of 0.5mm for all ranges in class H. Application and Benefits General Tolerance - ISO 2768 1 & 2 - ZEISS Quality Forum

"ISO 2768-mh allows anything to be sloppy." Reality: A 0.2mm deviation on a 6mm shaft is a 3.3% error. For general machinery, that is acceptable. For a wristwatch, it is a disaster. The standard is not "sloppy"; it is "economical."

If an entire part does not require high-precision form and position (the "H" class), forcing the shop to meet these tight geometric requirements can skyrocket production and inspection costs.

The first letter corresponds to and dictates the tolerance class for linear dimensions, external radii, and chamfers. The letter "m" stands for Medium . Other options in this category include (coarse), and
