Note: "H" stands for "precision" geometric tolerance class.
To use the chart, follow these steps:
The ISO 2768-MH tolerance chart is a valuable resource for engineers and manufacturers, providing a set of general tolerances for linear and angular dimensions. By understanding and applying the tolerances outlined in this chart, designers and manufacturers can ensure that their parts and components fit together seamlessly, while also minimizing costs and maximizing efficiency. Whether you're working in aerospace, automotive, or medical devices, the ISO 2768-MH tolerance chart is an essential tool to have in your toolkit. iso 2768-mh tolerance chart
These tolerances apply to angular dimensions, usually expressed in degrees and minutes.
