what is an h6 tolerance

by Mrs. Alycia Rolfson II Published 3 years ago Updated 3 years ago

A hole that has a 0.030” diameter will have an h6 tolerance of (+0.0000,-0.0002), while a 1.00” hole with have an h6 tolerance band of (+0.0000,-0.0005). It is important to note that most sources list IT tolerances in millimeters, while the graph below has been translated to inches.Aug 14, 2018

What is the H6 tolerance of a hole?

For example, a tolerance with the number 6 will have a smaller tolerance range than the number 7, but larger than the number 5. This range is based on the size of the shank. A hole that has a 0.030” diameter will have an h6 tolerance of (+0.0000,-0.0002), while a 1.00” hole with have an h6 tolerance band of (+0.0000,-0.0005).

What does H6 mean on a bolt?

What is an 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 an H6 shrink fit holder?

With an h6 shrink fit holder, the result is a secure connection with stronger gripping power. However, only certain shanks are able to be used with this type of holder.

What is the tolerance range for a hole in a pipe?

This range is based on the size of the shank. A hole that has a 0.030” diameter will have an h6 tolerance of (+0.0000,-0.0002), while a 1.00” hole with have an h6 tolerance band of (+0.0000,-0.0005). It is important to note that most sources list IT tolerances in millimeters, while the graph below has been translated to inches.

What does h6 tolerance mean?

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. 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).

What is h6 clearance?

G7/h6. Location. Very close clearances for precise accuracy requirements, which can be assembled without force and will turn & slide when lubricated, e.g., precise guiding of shafts.
