The following Engineering calculator will show the plus and minus tolerance for the specific ISO 286 Shaft tolerance data. Enter your desired preferred tolerance grade and the nomial size. Also see Table of Hole Tolerances per. ISO 286

The following links are to Mechanical Tolerance Table Charts for Standard Shaft Hole Fits per ANSI 4.1. The size ranges given are for typical size ranges utilized within industry.

Fundamental deviation of shafts Chart. Click the Tolerance Link (e.g., g ) to get the Full & Accurate charts for a specific deviation in Inch and Metric units; Click icons to show all columns of the entire diameter range (0-3,150 mm)

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. The usage of these tolerances is advised for economic reasons. Loose running fit for wide commercial tolerances or allowances on external members.

The hole basis fits have four preferred hole tolerances (H11, H9, H8, and H7); the shaft basis fits have four preferred shaft tolerances (h11, h9, h7, and h6) as shown in Table 6-1. The above shaft tolerances are now covered in the new ANSI B32.100-2005 standard.

Limits, fits, allowances and tolerances charts and calculators according to ISO 286-1 (2010), ISO 286-2 (2010) ,ANSI B4.2 (1978), ANSI B4.1-1967 (R2004) standards which are based on metric and inch units.
