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 second 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. A first generally planar side wing extends laterally from the central barrel of the wing nut. A second generally planar side wing extends laterally from the central barrel. The first side wing includes a first opening for receipt of a first wire tie leg, and the second side wing includes a second opening for receipt of a second wire tie leg. The wing nut is independently rotatable relative to the shaft to angularly orient the wings and thus the openings as desired.
