Similar Values for XZ Shear and 1st Principle Stress

  I'm currently conducting an analysis on the the effect of geometry on a square shoulder with fillet in a circular shaft under torsion, when doing the post processing I've noticed that my element solution for max stress in the XZ plane is almost identical to the nodal solution for the 1st principal stress.
  
  Can anyone explain why that is?
  
  Thank You,

  Please add an image to show the geometry and the location of the stress you are describing along with the coordinate axes.
