ISO 2768 is the internationally recognized standard for "General Tolerances," providing default tolerance values for dimensions that do not have individual tolerance indications on engineering drawings. By adopting this standard, manufacturers and designers communicate clearly, reduce documentation time, and ensure consistent quality across global supply chains.

ISO 2768-1 applies to dimensions that are produced by metal removal (e.g., CNC machining) or are formed from sheet metal. It provides four distinct tolerance classes, allowing you to select the level of precision that best matches your part's function and your manufacturing capabilities. iso 2768 general tolerances pdf exclusive

Angular tolerances vary based on the nominal length of the shorter side of the angle:

ISO 2768 is an indispensable tool for engineers, designers, and manufacturers worldwide. By providing standardized default tolerances for both dimensional and geometrical features, it simplifies technical drawings, reduces documentation time, and ensures consistent communication across global supply chains.

This means the drawing uses Medium (m) tolerances for dimensions (Part 1) and K tolerances for geometric features (Part 2). This combination is the industry standard for general CNC machining and sheet metal fabrication. It provides four distinct tolerance classes, allowing you

Selecting the right class is a balancing act between functional requirements and manufacturing cost. Over-tolerancing can dramatically increase production and inspection costs, while under-tolerancing can lead to assembly and performance failures.
