ABSTRACT:
A thread-cutting screwed dowel has an essentially cylindrical, sleevelike dowel body with an axial bore and with a load engagement device disposed in the interior of the dowel body, for example with a female thread. On its outer face, the dowel body is equipped with at least one cutting edge, which extends helically along a majority of the outer face of the dowel body and protrudes radially past it. The helical cutting edge is embodied as a primary cutting edge and wraps around the dowel body over its length in at least three windings. Besides the load engagement device, an additional engagement is provided for transmitting a torque in the interior of the dowel body.
