Tolerance Pdf: Din 6930 M

Never use ISO 2768 for sheet metal. It does not account for springback or sheared edge deformation. Always specify DIN 6930 M on your sheet metal drawings.

The standard is divided into two primary parts: , which covers technical delivery conditions, and DIN 6930-2 , which specifies the actual tolerance values. The m (medium) tolerance class is the most commonly referenced accuracy grade, balancing manufacturing precision with cost-effectiveness.

These apply to lengths, widths, and hole diameters of flat parts. For the medium grade (m), typical limit deviations (± in mm) based on nominal size ranges include: Modulus Metal Up to 6 mm : ±0.1 to ±0.2 mm (depending on thickness). 6 to 30 mm : ±0.3 mm. 30 to 120 mm : ±0.5 mm. 120 to 400 mm : ±0.8 mm. 400 to 1000 mm : ±1.2 mm. Groupe TMA 2. Angular Dimensions for Flat Stampings (Table 3) Never use ISO 2768 for sheet metal

Note: For laser-cut parts, these values are often tighter, but the standard still mandates these maximum deviations for stamped features. The standard is divided into two primary parts:
