A force introduction fitting for lightweight constructional components comprises at least one radial force introduction surface, at least one axial force introduction surface, and at least one receiving means for holding the force introduction fitting and for introducing loads into the force introduction fitting. The radial force introduction surface and the axial force introduction surface enclose a hollow space. The radial force introduction surface and the axial force introduction surface form a single-piece component. Such a force introduction fitting can be produced with the use of a selective laser melting method. The force introduction fitting can thus be adjusted in a particularly flexible manner to the load conditions, comprises particularly advantageous materials characteristics and features a lightweight construction.
