Abstract:
1. A bonding washer for making an electrical connection between two metal pieces when the metal pieces are rigidly held together by a fastener with at least a portion of the bonding washer disposed between them, the bonding washer comprising a metal body member, which comprises: an opening through which a fastener can extend; a first body portion adjacent and substantially parallel to a second body portion; a first set of teeth, numbering one or more, formed on said first body portion and extending away from said body member in a first direction substantially perpendicular to said first and second body portions, each tooth of said first set having a distal edge; and a second set of teeth, numbering one or more, formed on said second body portion and extending away from said body member in a second direction substantially opposite said first direction, each tooth of said second set having a distal edge, wherein at least one tooth of said second set of teeth is substantially aligned with a tooth of said first set of teeth to define at least one pair of substantially aligned, diverging teeth, whereby, when a fastener extending through said opening is tightened with said first and second sets of teeth between the metal pieces, the distal edges of said teeth are forcibly embedded into the metal pieces to make electrical contact therewith.
