It is worth noting that the original DIN 6930 has been largely superseded by the international standard . However, the legacy of DIN 6930 is incredibly strong. Many older drawings still reference it, and many tool and die makers prefer the DIN 6930 tables because they are often considered slightly more intuitive for specific stamping applications compared to the broader ISO 13920. Consequently, the DIN 6930 tables remain a staple reference in workshops globally.
For bent flanges, Class M allows:
Why is this specific keyword so popular? Because the letter "M" represents the standard tolerance class for general engineering applications, making it the default assumption for most drawings. However, simply downloading a PDF chart is not enough; one must understand the metallurgical and mechanical principles behind the numbers to ensure functional parts and cost-effective production. din 6930 m tolerance pdf
Having the PDF is only half the battle. Here is how to apply it correctly: It is worth noting that the original DIN
This is where most quality disputes occur. Under , the permissible bow or warp per 100 mm length is 0.5 mm (total over 300 mm: max 1.5 mm). This is stricter than Coarse (1.0 mm/100mm) but looser than Fine (0.2 mm/100mm). Consequently, the DIN 6930 tables remain a staple
A common frustration among engineers is that official DIN standards are copyrighted and expensive (often €100+ per document). However, you can legally and freely access the essential tolerance tables in several ways:
