Iso 2768 General Tolerances Pdf Jun 2026

Imagine you design a steel bracket with the following features:

"General tolerances according to ISO 2768-mK"

The permissible deviations depend on the nominal size of the dimension. The larger the dimension, the larger the allowed tolerance zone. Table 1: Linear Dimensions (Except broken edges) Values are shown in millimeters (mm). Tolerance 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 (fine) m (medium) c (coarse) v (very coarse) Table 2: External Radii and Chamfer Heights Values are shown in millimeters (mm). Tolerance Class Over 3 to 6 Over 6 to 30 Over 30 to 120 Over 120 to 400 f (fine) m (medium) c (coarse) v (very coarse) Table 3: Angular Dimensions

Choosing "Fine" (f) for an entire assembly when "Medium" (m) is sufficient will drastically increase manufacturing rejection rates and production costs without adding functional value. Where to Download the ISO 2768 General Tolerances PDF Iso 2768 General Tolerances Pdf

Easy-to-read cross-reference matrices showing dimension ranges.

By using ISO 2768, designers and manufacturers can specify general tolerances for their parts and assemblies, ensuring that they are interchangeable and functional.

Keep in mind that accessing a PDF copy of the standard may require a subscription or a one-time payment. Imagine you design a steel bracket with the

Having a PDF version of these tables is essential for several reasons:

For large structures where high precision is impractical. Nominal Length Range (mm) m (medium) c (coarse) v (very coarse) Over 6 to 30 Over 120 to 400 Over 1000 to 2000

All unspecified linear and angular dimensions follow . All unspecified geometric features follow Class K . Why You Need an ISO 2768 General Tolerances PDF Tolerance Class Over 3 to 6 Over 6

Leo took the tablet, adjusted the title block to (Fine for linear, High for geometry), and sent the revised PDF back to the shop.

Many manufacturing websites, machine shops, and engineering universities offer quick-reference PDF charts summarizing the ISO 2768 tables for free download. While these quick-reference PDFs are highly convenient for day-to-day machining or modeling tasks, remember that they only contain data tables. They omit the critical explanatory text, definitions, and legal scope contained in the official, paid ISO document. Frequently Asked Questions (FAQ) What replaces ISO 2768?
