1. A workpiece-contact element comprising:
an attachment side having one or more fastener-stabilizing-assembly-receiving cavity surfaces directly connected to a surface of the attachment side and defining a fastener-stabilizing-assembly-receiving cavity;
a workpiece-contact surface;
an outer cylindrical side surface; and
one or more fastener-exit surfaces defining a fastener-exit throughbore having a longitudinal axis and extending through the workpiece-contact surface,
wherein the workpiece-contact surface forms a protrusion extending away from the attachment side,
wherein the workpiece-contact surface is formed between the one or more fastener-exit surfaces defining the fastener-exit throughbore and the outer cylindrical side surface,
wherein the workpiece-contact surface radiates outwardly from the fastener-exit throughbore to the outer cylindrical side surface, the workpiece-contact surface comprising:
(a) a first at least partially annular flat section transverse to the longitudinal axis and having a first height from the attachment side,
(b) a second at least partially annular flat section transverse to the longitudinal axis and having a second height from the attachment side, said second height being greater than the first height, and
(c) a third at least partially annular section directly connecting the first flat section and the second flat section and extending away from the first flat section toward the longitudinal axis, wherein the second section, the third section, and the first section are directly connected in a linear progression extending away from the fastener-exit throughbore and ending at the outer cylindrical side surface.
