A beam clamp for attachment to a beam structure such as a side flange of an I-beam for suspending threaded hanger rods therefrom for installing plumbing and electrical apparatuses thereon. The beam clamp includes a generally C-shaped clamping member with a spaced apart pair of clamping arms and a connecting portion connecting the clamping arms together. The clamping arms of the clamping member define a space designed for receiving a portion of a beam structure therein. A first of the clamping arms has a threaded axial bore extending therethrough. A threaded bolt is threadably extended through the threaded axial bore of the first clamping arm into the space between the clamping arms of the clamping member. The connecting portion of the clamping member has hole therethrough extending between the first and second faces of the clamping member. A shaft is extended through the hole of the connecting portion. Coupled to either end of the shaft are first and second barrels each with a threaded bore therethrough.
