1. A bonding element to electrically connect a first and a second electrically conductive member, the bonding element comprising:
- an electrically conductive, substantially planar body located substantially in a first plane;
an electrically conductive first wall integrally formed with a first end of said body and extending substantially perpendicular to said body in said first direction, said first wall having at least one tooth spaced from said body and extending in said first direction; and
an electrically conductive second wall integrally formed with a second end of said body and extending substantially perpendicular to said body, said second wall having at least tooth spaced from said body in a second direction opposite said first direction, and said at least one tooth extending from said second wall in said first direction, said planar body, first wall and second wall forming a conductive path between said the at least one tooth of said first wall and first electrically conductive member and the at least one tooth of said second wall and second electrically conductive member.

Abstract
A bonding washer for making electrical connection between two metal pieces that are to be mechanically fastened together. The washer, to be interposed between the two metal pieces, may be constructed so as to fasten to one of the pieces before the two pieces are joined. Teeth on the washer, positioned at right angles to the plane of the washer, are forced into each of the two metal pieces when the fastener is tightened, making electrical connection between the two metal pieces.

5. A bonding element to electrically connect first and second electrically conductive members, the bonding element comprising:
-
a one-piece electrically conductive clip having a first, substantially planar section connected to a first end of a first connecting section and located substantially in a first plane, and at least one tooth extending outwardly from said first section; a second, substantially planar section connected to a second end of said first connecting section and located in a second plane spaced in a first direction from and substantially parallel to said first plane, and at least one second tooth extending outward from said second section; wherein said at least one first tooth in said first section extends outwardly from said first section in a second direction substantially opposite from said first direction and oriented for contacting the first electrically conductive member, and said at least one second tooth in said second section extends outwardly from said second section in said second direction and oriented for contacting the second electrically conductive member positioned between said first substantially planar section and said second substantially planar section, and where said at least one tooth of said first section and said at least one tooth of said second section are substantially tubular with a center axis extending substantially perpendicular to a plane of said first substantially planar section and said second substantially planar section. - View Dependent Claims (6, 7, 8, 9)

10. A bonding element for use with a first electrically conductive member and a second electrically conductive member, and a fastener for coupling said bonding element to the first electrically conductive member and the second electrically conductive member, said bonding element comprising:
-
an electrically conductive planar body having a first side and a second side, and at least one tooth extending from said planar body in a direction substantially perpendicular to a plane of said planar body; a tubular member extending from said second side of said planar body, said tubular body having an axial passage extending through said planar body for receiving the fastener, and an outer radial surface with a plurality of outwardly extending teeth, wherein said fastener is configured to axially compress said tubular body where said at least one tooth of said planar body engages said first electrically conductive member to make electrical contact and said plurality of teeth of said tubular body engage said second electrically conductive member to make electrical contact between said first and second electrically conductive members. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
