The ISO 2768-mK standard provides general tolerances for linear and angular dimensions (m) and geometrical features (K), ensuring consistent quality in manufacturing without requiring individual dimension callouts. This standard serves as a cost-effective, universally recognized guide for machining and fabrication. A detailed breakdown of these standards is available from SogaWorks .

If you are referencing an ISO 2768-mK PDF, you will typically utilize look-up tables. Here is a simplified example of how linear tolerances work under class "m": Tolerance Iso 2768 Mk Pdf
For a length up to 100mm, the tolerance is 0.2mm. The ISO 2768-mK standard provides general tolerances for
For 80% of mechanical components, the medium precision of ISO 2768 MK is the perfect balance between manufacturing cost and quality. Get your reference chart today, and never guess a tolerance again. f (fine) m (medium) c (coarse) v (very coarse)
There are many free versions of this standard circulating online, but many contain OCR errors or missing charts. To get an accurate :
