^ According to Chris McCauley, Editor-In-Chief of Industrial Press' Machinery's Handbook: Standard Tolerance '… does not appear to originate with any of the recent editions (24-28) of Machinery's Handbook, although those tolerances may have been mentioned somewhere in one of the many old editions of the Handbook.' ( 8:47 AM).

(All four places, including the single decimal place, are common knowledge in the field, although a reference for the single place could not be found.)

^ 2, 3 and 4 decimal places quoted from page 29 of 'Machine Tool Practices', 6th edition, by R.R.

In addition there is the difference between the deep draft and the stream bed or sea bed of a waterway.

In civil engineering, clearance refers to the difference between the loading gauge and the structure gauge in the case of railroad cars or trams, or the difference between the size of any vehicle and the width/height of doors or the width/height of an overpass as well as the air draft under a bridge. This method of standard tolerances is also known as Limits and Fits and can be found in ISO 286-1:2010 (Link to ISO catalog). For a shaft of the same size, h6 would mean 10+0−0.009, which means the shaft may be as small as 0.009 mm smaller than the base dimension and 0 mm larger. The actual amount bigger/smaller depends on the base dimension. The tolerances work in such a way that for a hole H7 means that the hole should be made slightly larger than the base dimension (in this case for an ISO fit 10+0.015−0, meaning that it may be up to 0.015 mm larger than the base dimension, and 0 mm smaller). H7/h6 is a very common standard tolerance which gives a tight fit.

For example: H7 (hole, tapped hole, or nut) and h7 (shaft or bolt). They are labelled with a letter (capitals for holes and lowercase for shafts) and a number. The standard (size) tolerances are divided into two categories: hole and shaft. When designing mechanical components, a system of standardized tolerances called International Tolerance grades are often used.
