A high-strength pintle anchoring system for a cavity wall is disclosed. The high-strength pintle anchoring system employs a partially compressively reduced veneer tie that is cold-worked with the resultant body partially having substantially semicircular edges and flat surfaces therebetween. The edges are aligned to receive compressive forces transmitted from the outer wythe. The partially compressively reduced veneer tie, when part of the anchoring system, interengages with the receptor portions of a wall anchor and are dimensioned to preclude significant movement lateral with or normal to the inner wythe.
