A method for producing a flange blank, comprising the following step: - producing a base body, wherein the base body comprises a fluid passage, which extends along a longitudinal axis, a support section having a first material thickness and a force-absorbing section having a second material thickness and the second material thickness is greater than the first material thickness; wherein the force-absorbing section is configured for the selective production of through-holes (15a - 15h, 17a - 17l) according to a first drilling pattern and/or a second drilling pattern; wherein the force-absorbing section, in a plane orthogonal to the longitudinal axis, has an outer contour which is preferably configured to be rotationally symmetrical about the longitudinal axis or mirror-symmetrical with respect to a plane of symmetry through which the longitudinal axis runs, wherein the outer contour of the force-absorbing section comprises rounded sections, wherein a plurality of first rounded sections have a first radius and a plurality of second rounded sections have a second radius, and the positioning, i.e. arrangement, as well as the size of the individual radii (R1, R2) are matched to the first drilling pattern and to the second drilling pattern, wherein the radii of the first rounded sections are coaxial with the central axes (13a-13h) of the through-holes of the second drilling pattern, and the radii of the second rounded sections are coaxial with the central axes (11a-11d) of the through-holes of the first drilling pattern. - producing a base body, wherein the base body comprises a fluid passage, which extends along a longitudinal axis, a support section having a first material thickness and a force-absorbing section having a second material thickness and the second material thickness is greater than the first material thickness; wherein the force-absorbing section is configured for the selective production of through-holes (15a - 15h, 17a - 17l) according to a first drilling pattern and/or a second drilling pattern; wherein the force-absorbing section, in a plane orthogonal to the longitudinal axis, has an outer contour which is preferably configured to be rotationally symmetrical about the longitudinal axis or mirror-symmetrical with respect to a plane of symmetry through which the longitudinal axis runs, wherein the outer contour of the force-absorbing section comprises rounded sections, wherein a plurality of first rounded sections have a first radius and a plurality of second rounded sections have a second radius, and the positioning, i.e. arrangement, as well as the size of the individual radii (R1, R2) are matched to the first drilling pattern and to the second drilling pattern, wherein the radii of the first rounded sections are coaxial with the central axes (13a-13h) of the through-holes of the second drilling pattern, and the radii of the second rounded sections are coaxial with the central axes (11a-11d) of the through-holes of the first drilling pattern. wherein the force-absorbing section is configured for the selective production of through-holes (15a - 15h, 17a - 17l) according to a first drilling pattern and/or a second drilling pattern; wherein the force-absorbing section, in a plane orthogonal to the longitudinal axis, has an outer contour which is preferably configured to be rotationally symmetrical about the longitudinal axis or mirror-symmetrical with respect to a plane of symmetry through which the longitudinal axis runs, wherein the outer contour of the force-absorbing section comprises rounded sections, wherein a plurality of first rounded sections have a first radius and a plurality of second rounded sections have a second radius, and the positioning, i.e. arrangement, as well as the size of the individual radii (R1, R2) are matched to the first drilling pattern and to the second drilling pattern, wherein the radii of the first rounded sections are coaxial with the central axes (13a-13h) of the through-holes of the second drilling pattern, and the radii of the second rounded sections are coaxial with the central axes (11a-11d) of the through-holes of the first drilling pattern.
