Angular tolerances are specified by , independent of the nominal angle value.
"ISO 2768-mK," Elias read aloud. "We looked at the 'm'. That covers linear dimensions—lengths, widths, heights. But that second letter... 'K'. That covers geometrical tolerances. Straightness, flatness, symmetry." iso 2768-m tolerances
The suffix refers to the Medium tolerance class, which is the most commonly used class for general engineering applications (between "fine" (f) and "coarse" (c)). Angular tolerances are specified by , independent of
Example: A shaft of length 75 mm (without individual tolerance) under ISO 2768-m allows a deviation of (actual length: 74.7 mm to 75.3 mm). Angular tolerances are specified by
