General Tolerance Iso 2768-mk -

ISO 2768-mk is a "general" standard. You should never rely on it for: High-precision fits (e.g., H7/g6).

In the world of precision manufacturing, specifying every single dimension with a dedicated tolerance would make technical drawings cluttered and nearly impossible to read. To solve this, engineers use general tolerance standards. The most common among these is . general tolerance iso 2768-mk

The designation consists of two separate parts that define the accuracy level for different features: ISO 2768-mk is a "general" standard

Part 2 focuses on the "form" of the part. There are three classes: H, K, and L. The class is the medium-level requirement for geometry. preventing over-processing and reducing costs.

It signals to the machine shop that standard workshop accuracy is sufficient for non-critical areas, preventing over-processing and reducing costs.
