Abstract
Abstract The expansion sleeve (10) of the expansion dowel, having a hole (13) tapering towards the front end (11), is provided in the tapering region with outwardly embossed beads (15). These beads (15) have a width (b) which increases towards the front end (11), as a result of which flanks (16, 17) are formed which are inclined towards the longitudinal axis of the sleeve and are turned towards the rearward end (12) of the expansion sleeve (10). These flanks (16, 17) lead to working surfaces which act against the direction of withdrawal and hence ensure adequately large anchoring values in all applications. <IMAGE>
