The Basics of General Tolerance Standard – ISO 2768-mK - Eurotools

The lowercase letter represents the tolerance class for linear dimensions (lengths, radii, diameters) and angular dimensions. ISO 2768-1 defines four accuracy classes: f – Fine m – Medium c – Coarse v – Very Coarse

But what exactly does it mean, and why is it the industry standard? Let’s break it down. What is ISO 2768-mK? general tolerance iso 2768-mk

This prevents "over-tolerancing," which can lead to unnecessarily high manufacturing costs by requiring tighter precision than the part's function demands. Exceptions: This public link is valid for 7 days

This part of the standard covers lengths, diameters, radii, and angles. The "m" (medium) class is the industry's "sweet spot," balancing functional accuracy with cost-effective manufacturing. Linear Dimension Tolerances (mm)

Angular tolerances vary based on the length of the of the angle. These values apply to all untoleranced angles on the drawing.

: Refers to ISO 2768-2 , which defines geometric tolerances such as flatness, straightness, and perpendicularity. When to Use This Callout Can’t copy the link right now

is an international standard for general tolerances used to simplify technical drawings by providing default limits for dimensions and geometric features that do not have specific tolerance markers . 🛠️ What "mK" Means

If you are working with a (like plastics) that might require different tolerance considerations.

Symmetry limits apply to parallel features or slots that share a central datum plane. Nominal Length Range (mm) Symmetry Tolerance (mm) for Class "k" Over 100 to 300 Over 300 to 1000 Over 1000 to 3000 4. Run-Out (Circular Run-Out)
