AbstractA mounting arrangement and method of manufacture for clamping synthetic resin panels to a workpiece such as a vehicle metal substructure. A composite joint pad has a plate-like metal bushing pre-molded therein. The bushing comprises a raised central embossment having an exposed portion terminating in an arcuate sectioned rim extremity positioned a predetermined distance outwardly from the bonding face of the pad. Upon the bushing exposed embossment being received in a panel aperture, the pad's face is bonded to a panel mating surface with the rim flush with an adjacent surrounding surface of the panel. This enables the pad's arcuate sectioned rim to be clampingly attached to the substructure by means of a threaded fastener being overdriven in the bushing stem without causing stress on the panel.
