Patent ID: 7676893

Claim:
A fastener adapted to removably mount an object in a mounting aperture of a panel, the fastener comprising: a fastener body having two opposing side members and defining a second aperture configured to accept at least a portion of the object; at least one elastic abutting flange defining an exterior concave portion extending a width of said abutting flange and configured to engage an inner surface of the mounting aperture when the fastener is inserted into the mounting aperture, the elastic abutting flange being disposed between the fastener body and the mounting aperture; corrosion resistant coating; and a sulfur-containing silencer plating directly overlying a portion of the corrosion resistant coating; said silencer plating being a dry lubricant which is stable in air and that relieves stress between the fastener and the mounting aperture to facilitate relative movement between the fastener and the mounting aperture, said fastener having an insertion force to insert the fastener within the mounting aperture and an extraction force needed to remove the fastener from the mounting aperture, said extraction force being more than the insertion force.
