How to read average stress from a surface?

Dear all,

 

I'm dealing with a problem regarding an average stress assessment.
I have modeled a pretensioned and loaded screw for which I have calculated analytically nominal stress.
How can I read an average stress state from a surface presented in the figure?
It can't be the average value from selected nodes as the mesh might be not evenly done.
Ideally I would like to have a tool which extracts an average value directly from a plane/surface.

Thank you in advance for help.

 

Best regards
Jakub
