How to perform stress analysis on a part with screws and shear pins?

I am currently trying to analyze a part that will have 4 screws and 2 shear pins connecting it to another part of an assembly. The assembly I am trying to analyze is shown in the pictures.

The problem that I am having is that I do not know for sure which items or surfaces to fix. I want to not only analyze the main part, but I also want to analyze the 4 screws and shear pins with it.

The analysis that I am showing in the pictures below was completed by fixing the surface tips of the 4 screws and 2 shear pins protruding through the part. This causes the screws and shear pins to act as if they were beams which is not correct, hence the high concentrations of stress on the screws and shear pins.

How do I correctly anlalyze this part INCLUDING the screws and pins?

Thanks in advance,
