The bonding washer includes an electrically conductive body and at least one piercing member extending from a bottom surface of the body. An extended member extends from the electrically conductive body in a direction away from the bottom surface of the body. ## Claims ### Claim 1 A bonding washer comprising: an electrically conductive body having a top surface, a bottom surface, and a fastener receiving portion for receiving a mounting fastener; at least one piercing member having a portion integral with the bottom surface of the body and a raised surface extending from the portion integral with the bottom surface of the body; and at least one extended member extending from the body in a direction opposite the at least one piercing member. ### Claim 2 (depends on 1) The bonding washer according to claim 1, wherein the body is substantially planar. ### Claim 3 (depends on 1) The bonding washer according to claim 1, wherein the at least one extended member extends from one end of the electrically conductive body. ### Claim 4 (depends on 1) The bonding washer according to claim 1, wherein the at least one extended member comprises two extended members, and wherein one extended member extends from one end of the electrically conductive body and the other extended member extends from another end of the electrically conductive body. ### Claim 5 (depends on 1) The bonding washer according to claim 1, wherein the at least one extended member prevents rotation of a wire termination relative to a structure when securing the bonding washer to the structure. ### Claim 6 (depends on 1) The bonding washer according to claim 1, wherein the at least one piercing member comprises a single tooth. ### Claim 7 (depends on 1) The bonding washer according to claim 1, wherein the at least one piercing member comprises a single tooth having a serrated distal end. ### Claim 8 (depends on 1) The bonding washer according to claim 1, wherein the fastener receiving member comprises an aperture. ### Claim 9 (depends on 1) The bonding washer according to claim 1, wherein the at least one piercing member has an aperture through the raised surface. ### Claim 10 A bonding washer comprising: an electrically conductive body having a top surface and a bottom surface; a plurality of piercing members, each piercing member having a portion integral with the bottom surface of the body and a raised surface extending from the portion integral with the bottom surface of the body; a plurality of gripping members extending from the top surface of the body; and at least one extended member extending from the electrically conductive body in a direction opposite the piercing members. ### Claim 11 (depends on 10) The bonding washer according to claim 10, wherein the electrically conductive body is substantially planar. ### Claim 12 (depends on 10) The bonding washer according to claim 10, wherein the at least one extended member extends from one end of the electrically conductive body. ### Claim 13 (depends on 10) The bonding washer according to claim 10, wherein the at least one extended member comprises two extended members, and wherein one extended member extends from one end of the electrically conductive body and the other extended member extends from another end of the electrically conductive body. ### Claim 14 (depends on 10) The bonding washer according to claim 10, wherein the extended member prevents rotation of a wire termination relative to a structure when securing the bonding washer to the structure. ### Claim 15 (depends on 10) The bonding washer according to claim 10, wherein each of the plurality of piercing members comprises a single tooth. ### Claim 16 (depends on 10) The bonding washer according to claim 10, wherein each of the plurality of piercing members comprises a single tooth having a serrated distal end. ### Claim 17 (depends on 10) The bonding washer according to claim 10, further comprising a fastener receiving portion for receiving a mounting fastener. ### Claim 18 (depends on 10) The bonding washer according to claim 10, wherein each piercing member has an aperture through the raised surface. ### Claim 19 A bonding washer comprising: an electrically conductive body having a top surface, a bottom surface, an aperture for receiving a mounting fastener, and a plurality of piercing members, each piercing member having a portion integral with the bottom surface of the body and a raised surface extending from the portion integral with the bottom surface of the body; and at least one extended member extending from the electrically conductive body in a direction opposite the piercing members. ### Claim 20 (depends on 19) The bonding washer according to claim 19, wherein the electrically conductive body is substantially planar. ### Claim 21 (depends on 19) The bonding washer according to claim 19, wherein the at least one extended member extends from one end of the electrically conductive body. ### Claim 22 (depends on 19) The bonding washer according to claim 19, wherein the at least one extended member comprises two extended members, and wherein one extended member extends from one end of the electrically conductive body and the other extended member extends from another end of the electrically conductive body. ### Claim 23 (depends on 19) The bonding washer according to claim 19, wherein the extended member prevents rotation of a wire termination relative to a structure when securing the bonding washer to the structure. ### Claim 24 (depends on 19) The bonding washer according to claim 19, wherein each of the plurality of piercing members comprises a single tooth. ### Claim 25 (depends on 19) The bonding washer according to claim 19, wherein each of the plurality of piercing member comprises a single tooth having a serrated distal end. ### Claim 26 (depends on 19) The bonding washer according to claim 19, wherein each piercing member has an aperture through the raised surface.
