How to join meshed solids to a bigger meshed solid surface for stress analysis?

I am trying to do some stress analysis and need help on how to join two or more than two meshed solids together prior to the analysis. 

 

Thanks

Without more info about the model, the best option would be contact with glue option as long as you are not interested in stresses at the area where the glue is being defined.

What is I want the stress states near the joints or contacts? Is there a
better or different way to account for this?

In this case the meshes should match (conforming mesh).

Meshes matching in the sense that the element size should be same on every solid?

Yes. In this way you can merge the nodes

Suppose I just want to apply constraints on the indicated site(only at the nodes that would typically be under the head screws), how do I accomplish that thing?

If your are interested just in the overall behaviour of the compoenent (displacemnet and stresses far away from this area) you can fixed simply the whole.
