ABSTRACT:
An anchor member to be fixed in a borehole by a permanently hardenable mass is formed as a sleeve-like member with the outside surface deformed inwardly at axially and circumferentially spaced areas so that the inside surface is deformed into a multi-sided cross-section. The inside surface can be four-sided with the inwardly deformed areas increasing the anchoring effect and preventing turning of the member when a fastening element is threaded into its trailing end. The sleeve-like member is closed at its leading end to avoid the hardenable mass from flowing into the member.
