It is upon Pitch Diameter that tolerance limits are based to establish Class of Thread. “H” means that pitch diameter is on the high side of basic. In the chart on this page we have illustrated the difference between tap and product limit, using
ISO Hole Tolerances (ISO 286-2) (3mm-400mm): ISO Hole Tolerances for chart given below shows range between 3mm to 400mm. Nominal Dimension and Tolerance Zone for Holes are in mm (Metric). ISO Hole Tolerances help the manufacturer to machine the parts with specified litims given by engineer.

H limits are used to properly size a tap for the threaded hole to be produced. They are selected based upon the tolerance required for the part. These tolerances are defined by the symbols class 1B, 2B, or 3B. ISO chart for holes limit and fit. Application of ISO fitting and limit chart, H7.g6
Allowed tolerances are only slightly larger than those of the mating bearing shown as a combination of a letter and a single digit number such as m6 and H7. Table XVII Radial Clearance for ISO Cylindrical Roller Bearings Straight Bore
Choosing standard sizes and applying proper tolerances to dimensions are among the important aspects in the design processes. ❖ The Table gives the Total Tolerance values for IT Grades from IT1 to IT18: For clearance fits: c, d, f, g, & h.

TAP SIZE: are designated by the letter H (high) above basic pitch diameter, or L P.D., (see Chart 1B). The tolerances according ISO 286 are defined up to 3150mm or up to 500mm dependend on the selected tolerance field.
