Iso 2768 Fk -

A common notation might look like:

Note: The full standard also includes "m" (Medium) and "c" (Coarse) for linear, and "L" (Coarse) for geometric.

Under the class, tolerances are extremely tight to ensure high-accuracy assemblies. Below are the permissible deviations (in mm) for various nominal length ranges: Nominal Length Range (mm) Fine (f) Tolerance Over 3 to 6 Over 6 to 30 Over 30 to 120 Over 120 to 400 Over 400 to 1000 Source: ZEISS Quality Forum ISO 2768-K: Geometrical Tolerances General Tolerance - ISO 2768 1 & 2 - ZEISS Quality Forum

: When you see "FK" in the context of ISO 2768, it refers to fine tolerances for linear dimensions ( f ) and geometrical tolerances ( K ), indicating a more precise requirement for both size and form/geometric accuracy. A common notation might look like: Note: The

: The "f" stands for "fine," the most precise of the four classes (f, m, c, v). It governs sizes like diameters, radii, and distances.

Angular tolerances: ± 0°20' for lengths up to 120mm. Below are the permissible deviations (in mm) for

Assuming FK corresponds to a specific tolerance class, here's a general outline:
