To extract the forces and moments going through a bolted connection, a simple approach is to use a Fixed Joint. Put the joint coordinate system at the center of the circular edge at the interface between the two bodies being fastened. In the Solution, output the Joint forces and moments going through that Fixed Joint. If you have solid elements, you would scope the mobile side of the joint to the cylindrical face of the hole in one side and the reference side of the joint to the cylindrical face of the hole in the other face. You don't model the bolt at all during force extraction.
After you have the forces and moments going through the fixed joint from the Random Vibe solution, build a Static Structural model, delete the Fixed Joint and add a 3D bolt model with pretension applied to show how the bolted connection can support the forces and moments.
