To apply this standard, add a note in the title block of your engineering drawing:

"GENERAL TOLERANCES ISO 2768-mK"

This single line replaces dozens of individual tolerance boxes, cleans up the drawing, and clearly defines the acceptable limits for the manufacturer.

Conclusion: ISO 2768-mK is the "Goldilocks" of machining tolerances—not too tight (expensive), not too loose (non-functional). It is perfect for 80% of standard mechanical parts. Tolerance Iso 2768 Mk Pdf

The keyword "ISO 2768 MK" refers to a specific combination of tolerance classes from the two parts of the standard.

Therefore, "ISO 2768 MK" means:

The designation ISO 2768-mK is a combination of two distinct parts of the standard. Because ISO 2768 is split into two functional sections, the suffix "mK" tells the manufacturer which tolerance class applies to both linear dimensions and geometric deviations. | Standard | Region | Key Difference |

ISO 2768 is an international standard for General Tolerances. It applies when individual tolerances are not explicitly specified on a drawing.

ISO 2768-mK combines two tolerance classes:

This combination is the most common default tolerance for machined parts, offering a balance between manufacturing cost and precision.

⚠️ Note: ISO 2768 was withdrawn and replaced by ISO 22081:2021 in many regions, but it remains widely used in legacy drawings, workshops, and supply chains. "GENERAL TOLERANCES ISO 2768-mK"

Under ISO 2768-2, if a drawing uses the "K" class, the general runout tolerance is equal to the general tolerance for diameter (from the M class) but capped typically at the K class values.

ISO 2768 is an international standard titled "General tolerances for linear and angular dimensions and geometrical tolerances." It is published by the International Organization for Standardization (ISO).

The standard simplifies engineering drawings by allowing designers to specify general tolerances without having to annotate every single dimension individually. If a specific tolerance is not listed next to a dimension, the "general tolerance" applies.

In the world of technical drawing and precision manufacturing, communication is everything. A single missing decimal point or an incorrectly assumed tolerance can lead to scrapped parts, costly rework, and delayed projects. This is where ISO 2768 becomes the silent guardian of global engineering.

Among the various complexity classes within ISO 2768, "MK" is the most frequently specified designation on 2D drawings. If you have ever searched for a Tolerance ISO 2768 MK PDF, you are likely an engineer, a CNC machinist, or a quality inspector trying to decipher what "General Tolerance ISO 2768-mK" means on a blueprint.

This article provides a complete breakdown of ISO 2768 MK, explains the difference between the "m" and "K" classes, discusses how to interpret the standard, and explains why having an official ISO 2768 MK PDF reference table is essential for your workshop.
