ABSTRACT OF THE DISCLOSURE A curtain-wall masonry veneer anchor system provides tolerances for accommodating installation misalignment and similarly for accommodating in-service load stresses while at the same time preventing loosening in service, even when installed through sheathing/or insulation covering wall structure to which the system is affixed, such as a masonry wall or metal stud or structural steel. A threaded stud is provided, either coarse- threaded along the length for self-tapping in a pre-drilled hole in masonry, or self-drilling and self-tapping for one operation affixation in steel studding or in structural steel; a fastener barrel has at one end a threaded hole receiving the stud and surrounded by teeth in a radial face arranged for routing away sheathing or insulation as the threaded stud screws into a wall, preventing crushed sheathing or insulation from causing loosen- ing and backing out under service loads; novel tie configuration connects with an eye in the fastener barrel outer end and accom- modates to the various rotational positions at which the fastener barrel may tighten in wall structure.
