A tolerance river for highly stressed riveted joints possessing a shank (3) whose length is harmonized with the two components to be joined, followed by a retaining piece (5) interacting with a retaining collar and provided with grooves (9) on its circumference. An enveloping jacket (12) which links the root diameters d1, d2 of the grooves, widenes conically from the head of the tolerance rivet toward its opposite free end. The grooves (9) on the retaining piece (5) have decreasing groove width a1, a2, etc., and increasing asymmetry of the groove profile. The first groove (9) located at the retaining piece (5) of the tolerance rivet that is located after the shank (3) in the direction toward its free end, possesses rounded shaping r3 in the area of its root diameter d1 whose area (13) is strain-hardened.
