Abstract
The invention comprises a washer for establishing electrical continuity between two conductive members each having a non-conductive coating and which are secured together by threaded fasteners such as screws. The washer has projections that pierce the non-conductive coatings of the two conductive components as the threaded fasteners are tightened thereby establishing electrical continuity through the washer.
