General Tolerance Iso 2768-mk !!hot!! ✓

The designation "mK" combines two specific parts of the standard: "m" (Medium) : Refers to ISO 2768-1 , covering linear and angular dimensions. "K" (Medium) : Refers to ISO 2768-2

Symmetry ensures that opposing features align perfectly across a central datum plane. Reference Length Range (mm) Tolerance Class (Medium) over 100 to 300 over 300 to 1000 over 1000 to 3000 4. Run-Out (Circular Run-Out)

While Part 1 handles size, Part 2 handles the of the part. The K class provides standard control over how straight, flat, or perpendicular a feature must be. Straightness and Flatness

For angular dimensions, the general tolerances under class "m" depend on the length of the shorter leg of the angle: Length of Shorter Leg (mm) Permissible Deviation for Class "m" 120 to 400 2. The Uppercase "K" (Geometrical Tolerances)

Set at 0.6 mm for features up to 300 mm, increasing to 1.0 mm for larger features. Circular Run-out: Generally specified as 0.2 mm. Why Use ISO 2768-mK? general tolerance iso 2768-mk

Applying this standard is straightforward. It's typically indicated in the drawing's title block with a clear note, such as "". This note informs the manufacturer that all dimensions without explicit tolerances must conform to the rules of that standard.

It immediately signals to the manufacturer which dimensions are critical (those with custom tolerances explicitly written out) and which are standard fit features. How to Apply It on a Drawing

Controls the 90-degree relationship between surfaces (e.g., 0.6 mm for lengths up to 300 mm).

In summary, is an efficient system for defining the default precision of a part, providing a common language between designer and machinist. It is widely used in industries like automotive, aerospace, and general manufacturing, and represents a balanced choice for a broad range of applications. The designation "mK" combines two specific parts of

For class K, the general circular run-out tolerance is 0.2 mm . Why Use ISO 2768-mK?

Specifies "Medium" tolerances for linear and angular dimensions (such as lengths, widths, radii, and diameters).

These apply to most measured lengths, diameters, and depths, including step sizes and distances.

Linear dimensions include external sizes, internal sizes, steps, diameters, and distances. Nominal Size Range (mm) Permissible Deviation (mm) for Class 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 External Radii and Chamfer Heights

Defines linear and angular tolerances. The 'm' stands for "medium" accuracy.
