ISO 2768 is designed to simplify technical drawings by specifying general tolerances for dimensions and features without individual tolerance indications. This ensures that the "customary workshop accuracy" is maintained for non-critical features, reducing drawing complexity and streamlining production. The standard is divided into two primary parts:

General tolerances for circular run-out in mm: Plastic parts usually follow ISO 20457

ISO 2768 is technically for metal removal (machining) or sheet metal. Plastic parts usually follow ISO 20457 .

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
