ISO 2768-fH indicates a drawing utilizing fine linear tolerances (f) and tight geometric tolerances (H). Why Use ISO 2768?
From Table 2 (Perpendicularity), for a nominal length up to 100 mm with Class K, the permitted perpendicularity deviation is .
"When applying these perpendicularity tolerances, the longer of the two sides forming the right angle shall be taken as the datum." iso 2768 general tolerances pdf exclusive
Used for precision components requiring high accuracy.

ISO 2768 is an international standard created by the International Organization for Standardization (ISO). It establishes a system of general tolerances for linear and angular dimensions without individual tolerance indications. Source: 13†L21-L22 ISO 2768 is an international standard
To properly apply these standards, the following note should be placed in the title block or general notes section of your technical drawing:
Understanding ISO 2768 General Tolerances ISO 2768 is the international standard used to simplify drawing indications for linear and angular dimensions. When a engineering drawing lacks specific tolerance callouts for a dimension, ISO 2768 dictates the allowable variations. This standard applies primarily to parts manufactured by metal removal or sheet metal fabrication.
Designers save hours by only calculating specific tolerances for critical mating features.
: This indicates standard medium tolerances for linear measurements (m) and medium geometric constraints (K). This is the most common specification for general CNC machining.
