ABSTRACT:
The anchor includes a stud holder having one end which threadably receives a threaded stud. A flat tongue-like driving head projects axially from the other end of the stud holder and is formed with an eye for receiving one end portion of a wire tie for establishing a positive lateral load connection between an outer masonry veneer wall and an inner supportive wall having a layer of insulation thereon. An integral, radially extending flange is formed at the inner end of the driving head and stabilizes the stud holder while the latter is being driven by a power-rotated socket. When the stud is fully driven, the flange seals a hole drilled in the insulation by the stud holder. The inner end of the stud holder includes cutting elements which enable the stud holder to drill effectively through both hard and soft insulation. The eye through the driving head is shaped so as to eliminate the need of establishing precise angular alinement between the driving head and the wire tie.
