2768 Mk -

This refers to geometrical tolerances defined in ISO 2768-2 . It sets general limits for characteristics such as: Straightness and flatness. Perpendicularity. Symmetry and circular run-out. Why Use ISO 2768-mK?

"mK" identifies the specific accuracy levels being used: "m" (Medium): Refers to Part 1 of the standard, covering linear and angular dimensions (like lengths, radii, and diameters). "K" (Class K): Refers to Part 2, covering geometric tolerances (such as flatness, straightness, and parallelism). LinkedIn +2 Why Manufacturers Love It Simplified Drawings: It keeps blueprints clean. Designers only need to highlight tolerances for "critical" features—those that absolutely must be exact for the part to function. Consistency: Whether you are machining in Berlin or Bangkok, ISO 2768-mK provides a universal language. A "medium" fit means the same thing to every machinist. Cost Efficiency: Over-tolerancing a part (making it more precise than it needs to be) is expensive. ISO 2768-mK sets a reasonable standard for non-essential features, preventing unnecessary labor and inspection costs. Fictiv +2 When NOT to Rely on It While ISO 2768-mK is a powerful tool, it isn't a "set it and forget it" solution. 10 sites Understanding ISO 2768-mK Tolerances for Engineers Dec 17, 2025 — 2768 mk
