A preformed hanger rod stiffening clip that improves the strength and stability of hanger rods to withstand compression forces. Precisely position screw holes enable the clamping legs of the clip to close completely when the fastening assembly is tightened. Washers on each side of the respective clamping legs deform the legs tightly around the stiffening member and the hanger rod which is disposed between the stiffening member and fastening assembly. It has been found that hole placement for a screw that is used to tighten the apparatus onto the hanger rod and stiffening member is critical. Misalignment of position of the screw openings greater than or equal to 0.001 inches results in a clip that will fail standard AISC compression tests.
