Iso 2768-mh — Tolerance Chart

ISO 2768 is a standard designed to simplify technical drawings by providing general, default tolerances for linear and angular dimensions, as well as geometric tolerances for features that do not have specifically listed tolerance indications. It is split into two main parts:

Or you can expand:

To ensure the standard is enforced, it must be clearly stated in the title block of the engineering drawing. A standard notation would look like this: This single line tells the manufacturer that: iso 2768-mh tolerance chart

Thus, choosing for angles is a deliberate decision to tighten angular control without resorting to individual callouts. ISO 2768 is a standard designed to simplify

Note: For nominal sizes below 0.5 mm, individual tolerances must be specified. individual tolerances must be specified.
