What is the meaning of h6 tolerance?
For example: H7 (hole, tapped hole, or nut) and h7 (shaft or bolt). H7/h6 is a very common standard tolerance which gives a tight fit. 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.
What is the tolerance of H7?
| ISO Tolerances for Holes (ISO 286-2) | ||
|---|---|---|
| Nominal hole sizes (mm) | ||
| H7 | +12 0 | +25 0 |
| H8 | +18 0 | +39 0 |
| H9 | +30 0 | +62 0 |
What is shaft tolerance?
Example; 7/8 inch Shaft, 25mm Shaft etc. BASIC SIZE : The size used when the nominal size is converted to the decimal and from which deviation are made to produce limit dimension. Tolerance equals the difference between lower and upper limit dimensions. Example; for 0.500-0.506 inch the tolerance would be 0.006 inch.
What is MMC LMC?
MMC is the condition of a feature which contains the maximum amount of material, that is, the smallest hole or largest pin, within the stated limits of size. LMC is the condition in which there is the least amount of material, the largest hole or smallest pin, within the stated limits of size.
What does minimum tolerance mean for a shaft?
– The minimum tolerance describes the smallest size the feature can be after the tolerance has been applied to the basic size. A lower case letters apply to shafts or male type features.
Can a tolerance be applied to a hole?
Tolerances can be applied to holes and shafts as well as other shapes. Also referred to as… British Standard for metric Limits and Fits The basic size of the feature or fit is the dimension the tolerances will be applied to: The zero line in the calculator. A tolerance is described using a letter followed by a number.

Which is the letter of the Tolerance grade?
The letter is the tolerance deviation, the number the tolerance grade. ex: H11 Each tolerance has a maximum and minimum. – The maximum tolerance describes the largest size the feature can be after the tolerance has been applied to the basic size.
