Abstract: The invention relates to a component (1) having a fastening region (2) for a threaded connection, wherein the component has a surface (3) having fiber material (5) embedded and integrated into a matrix (4) in at least one layer, wherein the fiber material has a fiber course substantially parallel to the surface, wherein the surface has a fastening opening (6) having a center axis (7) arranged at an angle to the surface and wherein the fastening opening is provided for an internal thread (8). In the region of the fastening opening, the fiber material lying parallel to the surface is deflected, starting from the surface, in such a way that the fiber course of the fiber material after the deflection is at an angle to the surface that approaches the direction of the center axis. Furthermore, a tube (9) is formed by means of the deflected fiber material. The invention further relates to a molded part and to a fastening part for such components.
