A sheet metal rivet, a body with a centerline and first side and second sides oppositely disposed with respect to the centerline; at least one first protrusion extending from the first side of the body and having a first width; and at least one second protrusion extending from the second side of the body and having a second width. The first and second widths are different or the at least one first and second protrusions are at least partially misaligned in a direction orthogonal to the centerline. In one embodiment, the at least one first and second protrusions include first and second pluralities of protrusions, respectively.

1. A sheet metal rivet, comprising: a body with: a centerline;a first side including first, second and third surfaces extending in a direction parallel to the centerline and aligned with each other;a second side oppositely disposed from the first side with respect to the centerline and including fourth, fifth, and sixth surfaces extending in the direction and aligned with each other;at least one first protrusion: extending from the first side of the body and having a first width;including a third side extending from the first surface; and,including a fourth side extending from the second surface; and,at least one second protrusion: extending from the second side of the body and having a second width;including a fifth side extending from the fourth surface; and,including a sixth side extending from the fifth surface, wherein the first and second widths are different or wherein the at least one first and second protrusions are at least partially misaligned in a direction orthogonal to the centerline. 2. The rivet of claim 1 wherein the at least one first and second protrusions include first and second pluralities of protrusions, respectively. 3. The rivet of claim 2 wherein the first plurality of protrusions includes first and second protrusions, wherein the second plurality of protrusions includes third and fourth protrusions, and wherein the first and second protrusions have different respective widths or the third and fourth protrusions have different respective widths. 4. The rivet of claim 2 wherein the first plurality of protrusions includes first and second protrusions, wherein the second plurality of protrusions includes third and fourth protrusions, and wherein a distance between the first and second protrusions is different than a distance between the third and fourth protrusions. 5. The rivet of claim 2 further comprising first and second ends through which the center line passes, wherein the first plurality of protrusions includes third and fourth protrusions, wherein the second plurality of protrusions includes fifth and sixth protrusions, wherein the third and fifth protrusions are between the fourth and sixth protrusions and the first end, and wherein respective distances from the first end to the third and fifth protrusions are different or wherein respective distances from the second end to the fourth and sixth protrusions are different. 6. The sheet metal rivet of claim 1, wherein: the at least one first protrusion includes a first protrusion and a third protrusion;the at least one second protrusion includes a second protrusion and a fourth protrusion;the third protrusion includes seventh and eighth sides extending from the second and third surfaces, respectively; and,the fourth protrusion includes ninth and tenth sides extending from the fifth and sixth surfaces, respectively. 7. The sheet metal rivet of claim 6, comprising first and second oppositely disposed ends, wherein: the centerline passes through the ends;the first surface is between the first end and the first protrusion;the fourth surface is between the first end and the second protrusion;the third surface is between the third protrusion and the second end; and,the sixth surface is between the fourth protrusion and the second end. 8. A method of stamping a sheet metal rivet, comprising: forming a body with a centerline and first side and second sides oppositely disposed with respect to the centerline;forming at least one first protrusion extending from the first side of the body and having a first width; and,forming at least one second protrusion extending from the second side of the body and having a second width, wherein the first and second widths are different or wherein the at least one first and second protrusions are at least partially misaligned in a direction orthogonal to the centerline. 9. The method of claim 8 wherein the at least one first and second protrusions include first and second pluralities of protrusions, respectively. 10. The method of claim 9 wherein the first plurality of protrusions includes first and second protrusions, wherein the second plurality of protrusions includes third and fourth protrusions, and wherein the first and second protrusions have different respective widths or the third and fourth protrusions have different respective widths. 11. The method of claim 9 wherein the first plurality of protrusions includes first and second protrusions, wherein the second plurality of protrusions includes third and fourth protrusions, and wherein a distance between the first and second protrusions is different than a distance between the third and fourth protrusions. 12. The method of claim 9 further comprising forming first and second ends in the body through which the center line passes, wherein the first plurality of protrusions includes first and second protrusions, wherein the second plurality of protrusions includes third and fourth protrusions, wherein the first and third protrusions are between the second and fourth protrusions and the first end, and wherein respective distances from the first end to the first and third protrusions are different or wherein respective distances from the second end to the third and fourth protrusions are different. 13. A damper, comprising: an axis of rotation;a first plate rotatable about the axis of rotation;a second plate rotatable about the axis of rotation;a plurality of springs engaged with the first plate; and,a sheet metal rivet, including: a body with a centerline and first and second sides oppositely disposed with respect to the centerline;first and second protrusions: extending from the first side of the body and through the first plate; and,including first and second distal ends extending past an exterior surface of the first plate; and,at least one third protrusion extending from the second side of the body.
