Problem with mesh convergence

Hi there,

 

I'm currently trying to do a mesh sensitivity analysis on an angle bracket, however, every time I attempt to get convergence I seem to be getting an increasing max stress on my von mises plot, to a point where the point of max stress actually shifts to  a different point in the vinicity of the max stress. I'm getting these stresses inside the bolt hole where I have fixtures. When I apply a smaller mesh size to this area through a mesh control, it just keeps getting bigger.

Two stress plots for two different mesh sizes are attached.

Any  help would be appreciated!
