ISO 2768 Tolerance Calculator

Modulus Metal ISO 2768 Calculator

Calculate General Tolerances According to ISO 2768-1 and ISO 2768-2 Standards

Table 1

Linear dimensions (except broken edges)

Table 2

Broken edges (radii & chamfers)

Table 3

Angular dimensions

Table 1: Permissible deviations for linear dimensions (external sizes, internal sizes, diameters, radii, distances, etc.)

Nominal Dimension (mm)

Tolerance Class

Table 2: Permissible deviations for broken edges (external radii and chamfer heights)

Nominal Dimension (mm)

Tolerance Class

Table 3: Permissible deviations for angular dimensions. Enter the length of the shorter side of the angle (not the angle value itself).

Shorter Side Length (mm)

Tolerance Class

Table 1

Straightness & Flatness

Table 2

Perpendicularity

Table 3

Symmetry

Table 4

Circular Run-out

Table 1: General tolerances on straightness and flatness. For straightness, use line length; for flatness, use the longer lateral length or diameter.

Nominal Length (mm)

Tolerance Class

Table 2: General tolerances on perpendicularity. Enter the length of the shorter side of the right angle.

Shorter Side Length (mm)
