ISO Shaft Tolerances (ISO 286-2)(3mm-400mm):


ISO Shaft Tolerances for chart given below shows range between 3mm to 400mm. Nominal Dimension and Tolerance Zone for Holes are in mm (Metric). ISO Shaft Tolerances help the manufacturer to machine the parts with specified limits given by engineer. ISO Shaft Tolerance limits is designated with lower case letter as shown in the chart and It is also described in previous pages.


Example: Nominal Size 3mm-6mm; -270μm= -270(10-3)=-0.270mm
