20120213611 | GRIPPING WASHER HAVING ONE OR MORE DEFORMABLE GRIPPING TABS AND METHOD FOR REDUCING FOREIGN OBJECT DEBRIS - A gripping washer includes a washer body having first and second rigid support surfaces. A fastener hole extends between the first and second rigid support surfaces. An inner washer perimeter extends around the fastener hole. One or more elastomeric gripping tabs are coupled with the inner washer perimeter. The one or more elastomeric gripping tabs extend inwardly into the fastener hole from the inner washer perimeter. The elastomeric gripping tabs are pliable relative to the first and second rigid support surfaces of the washer body and deform and grip the washer with a fastener passed through the fastener hole. By gripping a fastener with the elastomeric gripping tabs the gripping washer is anchored to the fastener and substantially prevents decoupling of the gripping washer from the fastener prior to installation (e.g., fastening with a work piece). Gripping of the fastener with the gripping washer thereby minimizes foreign object debris. | 08-23-2012 |
