Expanding anchor made of metal and placing tool therefor

摘要

The invention relates to an expansible anchor ( 1 ) made of metal for affixing a component to a substrate. Known expansible anchors ( 1 ) have an anchor element ( 3 ) with fixing means ( 4 ) and an expansion zone ( 5 ) of reduced diameter which widens in the direction of insertion of the expansible anchor. An expansion sleeve ( 6 ) having expansion tongues ( 8 ) and at least one cutter ( 9 ) for creating an undercut is mounted on the expansion zone ( 5 ) so as to be axially displaceable. In order to reduce the manufacturing costs for such an expansible anchor ( 1 ), the invention proposes that the expansion sleeve ( 6 ) consists of hardened steel and the predetermined bending lines ( 10 ) are straight. The invention also proposes a setting tool ( 2 ) for setting such an expansible anchor ( 1 ), which has key-surfaces ( 16 ), a driving surface ( 17 ) and an adapter device ( 18 ).
