An electrical connection includes an elongate stud defining a central longitudinal axis, and having a patterned segment, a shoulder, and a flange. The shoulder is generally circular in cross-section having one or more outwardly directed curved surfaces. The shoulder may have an outer continuous curved surface, an outer continuous undulating curved surface, an outer continuous undulating curved surface including alternating sectors of concave and convex regions relative to the longitudinal axis of the elongate stud. Convex regions of the shoulder define corresponding flutes whose cross sections each form a fraction of a first circle, and concave regions define corresponding lobes whose cross sections each form a fraction of a second circle. A diameter or radius of the first and second circles are the same. In an aspect, the diameters or radii of the first and second circles are different. The shoulder may be multilobular, pentalobular, hexalobular or octalobular.
