Thread eccentricity tolerance:
2A of the external thread and the thread of the modified 2B various elements, the concentricity of the joint
does not exceed the following limit
External thread
When the diameter is the largest and the largest diameter, the two thread elements must be concentric,
however, if the size is not round, the size is small, in the non round point, the diameter and diameter will
produce deviation
In the middle of the smallest, the largest diameter, the two elements of the total runout can not be greater
than the middle diameter tolerance;
The diameter of the largest, the largest diameter of the hour, the two elements of the eccentricity of the
full jump is not greater than the large diameter tolerance;
The diameter of the smallest, the largest diameter of the hour, the two elements of the total runout can
not be greater than the diameter of the tolerance tolerance
Internal thread
The smallest diameter, small diameter (minor diameter) the shortest, the two should be concentric, if the
path is not round or too large, the two elements of the total runout can not be greater than the size of the
path tolerance;
The maximum diameter of the path, the shortest path, the two elements of the eccentricity of the total
runout should not be greater than the median diameter tolerance
When the diameter is the smallest, and the path is the largest, the full runout of the two elements can not
be greater than the path.
