Stress convergence

Hi guys,

I'm running a simulation of an assembly and I'm interested in finding the stress on the cylindrical faces of the bolt holes.

Although the displacement converges, the stress at the bolt head and nut head keep rising - which means singularity.

I used bolt connectors with a pre-load of 40 Nm.

 

Can anyone have an idea of how should I deal with it?
