Abstract of the Disclosure Disclosed is a new fastening system particularly for fastening of fiber reinforced polyester/plywood panels to metallic structural members in sealing engagement through apertures. The system has a sealing capped nut for receiving in threaded engagement a bolt. Upon such engagement a formable shank portion of the sealing capped nut is deformed in a designed fashion to form a seal between the bolt and the aperture opening. The sealing capped nut and shank portion includes a tubular end formed of a deformable material, the shank having a length greater than those of the apertures in the article. An accompanying bolt insertable into the capped nut and has a hem forming surface so that when the members are assembled the surface readily deforms the tubular end and produces a radially extending, periphery continuous hem which engages around the aperture and is clamped into sealing engagement therewith by the clamping force of the bolt.
