With Fit (tolerance only), the Fit standards are not displayed. Select Show parenthesis to insert parenthesis around the tolerance values ( Fit with tolerance only).įor Fit or Fit with tolerance with both hole and shaft tolerances, you can select a display style. PREFERRED FITS AND TOLERANCES CHARTS (ISO & ANSI METRIC STANDARDS) Preferred. To specify tolerances manually, click the Hole Fit or Shaft Fit icon and type values in the Maximum Variation and Minimum Variation boxes.

These size charts do not compensate position or other GD&T location tolerances. This standard has been revised by ISO 286-1:2010 Abstract This part gives the bases of the ISO system of limits and fits together with the calculated values of the standard tolerances and fundamental deviations. Based on standard tolerances and limit deviations in accordance with ISO 286.

The advantage of letting the SOLIDWORKS software calculate the bilateral tolerance values for you is that if the dimension changes, the tolerances are updated automatically. Class of Tolerance Range for Holes M6 JS6 K5 M6 N6 P6 F6 F7 G6 G7 H6 H7 JS6JS7 K6 K7 M6 M7. Hole Basis is preferred for most manufacturing processes. The usage of these tolerances is advised for economic reasons. ISO and ANSI both group fits into three categories: clearance. Preferred Fits and Tolerances Charts (ISO) PREFERRED FITS AND TOLERANCES CHARTS (ISO & ANSI METRIC STANDARDS) Preferred fits and tolerance table for hole and shaft basis systems which are given in ISO 286-1 (2010) and ANSI B4.2-1978 standards. As Hole Basis and Shaft Basis Fit classifications in the international standards are not fully bidirectional, you may get a different list of suggested Fit choices (or an empty list) depending on the order in which you choose your designations. A limits, fits and tolerance calculator is also provided for practical assistance.
The Classification aid for selecting an appropriate Fit designation is either Hole Basis or Shaft Basis, depending on which Fit designation you choose first.
