Hey,

The mesh on the nut seems to be too coarse when comapred to the bolt. This results in less number of contacting elements between the bolt and the nut. Can you make the mesh on nut more comparable to the bolt and check if there is any improvement in stress distribution.
Also what is the goal of your study - is it to study the stresses generated on the bolt threads ??
Can you also check what the stress levels are a little away from that zone..

Regards,
