Abstract
An expansion dowel is formed of an axially extending sleeve (1) with a cylindrically-shaped outside surface. A setting tool for expanding the sleeve includes an axially extending handle part (2) holding an axially extending striking part (3). The handle part (2) has an axially extending recess (2b) with a concave-shaped base in its outside surface. The axial length (L) of the recess (2b) is substantially the same as the axial length (1) of the sleeve. A clearance-free seating of the expansion dowel into the recess (2b) indicates to the tool operator that a correct expansion dowel is being used with the tool for assuring a proper expansion of the dowel.
