Abstract

The anchor bolt for a building has a threaded section, a frusto-conical head and a polygonal cross section expansion sleeve (1) with an inner thread. The sleeve has frangible lines extending along the polygonal sides to allow the sleeve sectors to assume an oblique angle when expanded. The middle section of the polygon sides have a frangible line (3) formed along large channel recesses (8) extending along the sleeve.
