ABSTRACT:
An expansion dowel includes an axially extending sleeve with a leading end and a trailing end. The sleeve is conically shaped for at least an axially extending portion from the leading end with the conically shaped portion diverging outwardly toward the trailing end. Axially extending projections protrude outwardly from the outer surface of the conically shaped portion of the sleeve and have at least one axially extending flank with a planar surface inclined relative to the axis of the sleeve. The at least one inclined flank forms a working surface which acts against any pulling out force on the sleeve and ensures high anchoring values.
