<p>A fastener system (100,100') for securing a multi-layer panel (200) having a first surface adapted to be secured to a substructure (300), a second surface awash in a fluid flowing thereacross, and a plurality of spaced fastener-receiving holes arranged in a predetermined array in the second surface. Each fastener (100,100') includes a threaded shank (112,112') having a diameter smaller than any of the fastener-receiving holes, a load-bearing flange (124,124') located adjacent the shank having a diameter greater than the shank diameter (112,112') for pressing the first surface of the panel against the substructure (300), an unthreaded shank (130,130') extending away from the load-bearing flange (124,124') and having a diameter smaller than the threaded shank diameter, and a second flange (140,140') having a diameter greater than the diameter of the load-bearing flange (124,124'). The second flange (140,140') is located on the side of the unthreaded shank (130,130') opposite the load-bearing flange (124,124'), and functions to seat against a recessed region of the second surface of the panel. A surface (148,148') on the second flange (140,140') adjacent the unthreaded shank (130,130') engages with and seals against a correspondingly configured recess (248a,248b) in the panel second surface. <IMAGE></p> |
