A system includes a back up wall and a veneer wall spaced from the back up wall. An anchor shaft has a first end secured to the back up wall, and a free end of the shaft projects into a space between the back up wall and the veneer wall. A wing nut has a central barrel disposed on the shaft proximate the free end. The wing nut is spaced apart from a surface of the back up wall and has a generally planar wing extending from an end of the central barrel wherein the wing includes at least one opening for receipt of a wire tie. The wing nut is independently rotatable about the shaft to angularly orient the wings and thus the at least one opening as desired.
