<p>The invention relates to an injection anchor, to be secured in rock bores by means of setting binding agents and having a centre injection channel, retaining ribs on the circumferential-wall side and nuts screwed onto threaded end sections, and, to optimise the utilisation and manufacture, proposes that the thread (2) carrying the nuts extend uniformly over the entire length of the anchor while forming the retaining ribs and that it be designed in such a way that the width (x) of the thread root (G) merging in fillets (10) into the thread rib (11) is a multiple of the width (y) of the thread rib (11). <IMAGE></p> |
