Dependent claims

A conductor piercing fastening device comprising:

a fastening member having a shaft portion and a head portion, said shaft portion of said fastening member including a threaded lower portion;
a washer member being removably mounted about said shaft portion of said fastening member, said washer member including a disc-like member having a top side and a bottom side, and also including a plurality of tines being attached to and extending outwardly from said bottom side of said disc-like member, said disc-like member having a centrally-disposed hole extending therethrough, said centrally-disposed hole being adapted to receive said shaft portion of said fastening member therethrough;
and
a washer stopper member being securely attached about said shaft portion of said fastening member and being spaced from said head portion of said fastening member, said washer stopper member being an annular flange being securely attached about said shaft portion of said fastening member;
wherein said washer member is disposed between said head portion of said fastening member and said washer stopper member;
wherein said washer member comprises a disc-like member having a top side and a bottom side, and also includes a plurality of tines formed on said the bottom side thereof, said plurality of tines extending in a direction substantially perpendicular to a surface of said bottom side, each of said tines having a substantially conical shape;
wherein said plurality of tines extend in a direction substantially perpendicular to a surface of said bottom side;
wherein a line connecting tips of said tines forms a circle, the circle defined by said tips having a first diameter measurement;
wherein said washer stopper member has an outer perimeter with a second diameter measurement;
and
wherein said first diameter measurement is substantially equal to said second diameter measurement such that said washer stopper is adapted to press a conductor member against the tips of said plurality of tines.
