ISO 2768-fH indicates a drawing utilizing fine linear tolerances (f) and tight geometric tolerances (H). Why Use ISO 2768?

The are copyrighted documents sold by authorized standards organizations. While this article provides comprehensive tolerance tables for reference, the full standard includes additional informative annexes, definitions, and official wording that are essential for certification and legal compliance.

The standard defines four tolerance classes:

) directly next to that specific dimension. The general "mK" rule will handle the rest of the part. Creating an Exclusive Internal Reference Document

The ISO 2768 general tolerances PDF is an exclusive document that provides a comprehensive guide to the general tolerances for various types of dimensions. The PDF document is widely used by engineers, designers, and manufacturers to ensure that their parts and components meet the required specifications.

| Aspect | ISO 2768 | ISO 286 | |--------|----------|---------| | | General tolerances for linear/angular dimensions and geometrical features | Tolerances for cylindrical surfaces (shafts and holes) and fits | | Application | Default tolerances for dimensions without individual specification | Specified fits like clearance, transition, or interference (e.g., H7/g6) | | Use Case | General-purpose dimensions, non-critical features | Critical mating surfaces, press fits, bearing mounts | The general "mK" rule will handle the rest of the part

When manufacturing parts, knowing the standard is just the first step. If you are preparing to send files for production, you can:

: Used for parts where high precision is not required.

If a specific feature on that drawing requires a tighter fit—such as a bearing journal or a press-fit pin—the engineer must explicitly write out a tight tolerance (e.g.,

This means the right-angle feature can deviate up to 0.4 mm from exact 90°, which is sufficient for many general-purpose applications such as housings, brackets, and structural parts.

To solve this problem, the International Organization for Standardization introduced . This standard establishes engineering shortcuts by providing a system of general tolerances.

When both dimensional and geometrical tolerances are needed, the drawing notation combines both classes. For example:

Angular deviations are measured across the longest side of the angle and are expressed in millimeters per meter (mm/m):
