An aircraft fastener element, as a collar or nut, designed and constructed to produce improved fatigue performance in low shear transfer joints. The improved collar or nut has a bearing surface which abuts against the adjacent surface of the workpiece aperture in an initial predetermined area so that when the collar is swaged or the nut tightened and compressed the initial annular base is flattened to no more than approximately 1.25 D (D being the internal diameter of the nut or collar).
