Disclosed is a new fastening system particularly for fastening of fiber-reinforced polyester/plywood panels 14 to metallic structural members 16 in sealing engagement through apertures 18. The system has a sealing capped nut 10 for receiving in threaded engagement a bolt 12. Upon such engagement a formable shank portion 40 of the sealing capped nut 10 is deformed in a designed fashion to form a seal between the bolt 12 and the aperture 18 opening.

A fastener system for sealing and fastening apertured articles comprising first and second members providing interfitting means operable when said members are assembled to secure said members together, each member providing a clamping face which cooperate when said members are assembled and interconnected by said interfitting means to engage and clamp against opposite surfaces of said articles, one of said members providing a reduced diameter shank extending from its clamping face proportioned to extend into said apertures in said articles and providing a single-layer tubular end having a substantially uniform diameter formed of deformable material, said shank having a length greater than the length of said apertures in said articles, said clamping face on the other of said members providing roll hem forming means operating when said members are assembled to radially deform said tubular end and produce a radially extending peripherally continuous rolled hem having at least two radially extending layers which engages the adjacent surface of said article around said aperture and is clamped into sealing engagement therewith by said clamping face of said other member, said one member operating to produce a seal with the adjacent surface of said articles around said apertures and in cooperation with said shank thereof and said hem to create a full seal of said apertures when said members are assembled.
