Meaning of Thread Tolerance Class 6H

The tolerance zone for the internal thread of the 6H thread is between 0.058mm and 0.091mm, with high accuracy and a wide range of applications, which can ensure the firmness of the connector. 6H is a representation of the tolerance zone code. 6 represents the tolerance level, and H represents the internal thread.

The tolerance zone code is represented by numbers and letters (upper case letters for internal threads and lower case letters for external threads), such as 7H, 6g, etc. It should be noted that 7H, 6g, etc. represent thread tolerances, while H7, g6 represent cylinder tolerance codes.
