The beam element has no geometry to attach the bolt element to. The bolt element needs a circular edge which will have rigid element connection to the rigid link (which represents the bolt) attaching to the other part.
Model your 'beam' as a solid and it should work fine. CAUTION: heed the warning and ignore stress w/in a diameter of the bolt connection. (You could hand-calculate those.)
Arif, you need to right click on the beam body and select 'Treat as solid'.
