Abstract
An anchor rod for use as a composite anchor is secured in a receiving borehole by one of a hardenable or curable organic and inorganic mortar mass. The anchor rod has a means (3) at a trailing end region (2) for engaging a load. The anchor rod has an anchoring region (4) insertable into the receiving borehole and has a thread-like profiling (5) for interaction with the mortar mass injected into the receiving borehole. The thread-like profiling is a coarse screw thread (5) and has a thread pitch (s) which reduces in the axial direction from the leading end toward the trailing end of the anchor rod (1).
