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.
The Inch values shown in the table are conversion from the mertic values per ISO 286. you should expect about 0.1-0.5 thous errors wehn comparing with ANSI B4.1/4.2! The posision of H relative to the other Shaft deviations.

It provides a system of tolerances and deviations suitable for two types of feature: “cylinder” and “two parallel opposite surfaces”. The main intention of this code system is the fulfilment of the function fit.
