Iso 2768 Medium
💡 If a dimension is critical to the function of the assembly, label it specifically. For everything else, ISO 2768-m is the safest and most efficient bet for general machining.
ISO 2768 is divided into two parts:
General Tolerances ISO 2768-mK
In Part 2, the classes are labeled H, K, and L. Usually, "ISO 2768-m" is paired with "K." If your drawing says , it means: m: Medium tolerances for linear/angular dimensions. iso 2768 medium
