Bolts resultant force

Hi

I have a question. I am making a linear structural analysis for some parts and the results of forces on bolts are strange. Only 1 bolt out of 16, has significantly bigger force. It's weir, cause all bolts are same size, material nad theoretically they should have the same load as they are at same height of a cylindrical surface. All bolts are tightened.

You can see it on a photo which is attached.

What can be a problem, and how to solve it?

    Hi,

    Were 5 bolt/nut turns applied to all the bolts?

    Hi, I discovered that it was actually a problem with CAD model. In Solidworks, thread hole should be a positioning hole, not a straight tap type. Now my simulation runs well and results are close to approximated.

    Thanks for reply
