Enter your desired preferred tolerance grade and the nomial size. 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. Class of Threads, H Limits. Classes Of Threads There are (3) established Classes of Thread, designated in the unified series by adding: "A" for Screws and "B" for Nuts (or other intenal threads) to show definite limits and tolerances. Class 1B Thread Is wherea 1A screw can run in readily for quick and easy assembly. The hole is classified as 1B.

As an example, in sizes 1” and smaller, an H1 tap has a tolerance range of from basic to .0005” over basic; an H2 tap from .0005” over basic to .001” over basic, (see chart 1A on this page). In addition, metric threads are also designated in much the same way.

The usage of these tolerances is advised for economic reasons. Supplement: Preferred fits advised by ISO and ANSI standards Note-1: For coated threads, the tolerances apply to the parts before coating, unless otherwise stated. After coating, the actual thread profile shall not at any point transgress the maximum material limits for positions h or H.
