Tables for Determining Metric Tolerances

Table 9: Tolerances for outside dimensions (shafts)

Table 9 details tolerances for outside dimensions (shafts) based relative to the tolerance symbol. This table works the same
way as Table 7, but is pulled from a different source (ANSI standards) and details s6 and u6 fits. Pick the nominal size value
that is closest to the desired nominal size to determine the required tolerance range relative to the chosen tolerance symbol.

hole basis fiT [mm] hole:
example: nominal size: 24 [mm]
size range to be used: 18 to 30 F6 +0.033 (0.013mm range)
IsO-Grade no.: It6 24 +0.020
tolerance symbol: F6/h6 shaft:
Desired Fit: clearance Fit [mm]
this Gives: Allowance for hole: 0.013mm h6 0 (0.013mm range)
Allowance for shaft: 0.013mm 24 -0.013
