<p>An anchor has an anchor rod (3) which must be rotated during the setting of the anchor, an anchor plate (4), and an anchor nut (1). The screw thread in the anchor nut (1) matches the screw thread of the anchor rod (3) only for part of the threaded bore (13). Thus the anchor nut (1) can be screwed only a little further on the anchor rod (3) and can be used to rotate said rod during the setting of the anchor up to a specific torque. As soon as the anchor rod (3) fits tightly in the bore hole by means of cementing, mortar, or expansion, the anchor rod (3) forms a continuous thread in the threaded bore (13) when the anchor nut (1) is rotated relative to the anchor rod (3), such that the anchor nut (1) can be screwed finally so far down on the anchor rod (3) that said anchor nut fixes the anchor plate (4) in the final position on the substrate (7).</p> |
