  • Patent number: 8568072
    Abstract: A screw hole seal structure seals a screw hole (13) in molding a fiber-reinforced resin member (1) in which an insert member (4) provided with the screw hole (13) is integrally incorporated. In the structure, a screw member (5) is tightened in the screw hole (13). In the structure, an elastic seal member (6) is compressed within the screw hole (13), in an axial direction of the screw member (5), and is therefore deformed radially outwards by compression force that is created by tightening of the screw member (5), and an air-tight state of the screw hole (13) is maintained by deformation of the elastic seal member (6).

  • Patent number: 8475103
    Abstract: A sealing washer assembly includes a main washer with a bottom annular groove for a removable O-ring and a top recess for a sealing washer. A fastener such as a screw or bolt passes through the sealing washer and the main washer, into a hole in a mounting surface. When the fastener is tightened, the main washer is clamped to the mounting surface to create a metal-to-metal seal, the O-ring is deformed to create a seal between the main washer and the mounting surface, and the sealing washer is deformed to create a seal between the fastener and the main washer.

  • Publication number: 20130164096
    Abstract: A device for fastening equipment parts such as photovoltaic panels on a sandwich or single-shell building envelope using a plurality of fastening elements (20, 20?) in the form of bolts, which can be supported at least by a connection part (30, 30?) and on a load-bearing part (12) of the building or the building envelope. If an outer shell (14) is present, the fastening elements (20, 20?) can be guided through the outer shell (14) and supported on the load-bearing part (12) and/or the outer shell (14). Each fastening element (20, 20?) can be positively engaged with the connection part (30, 30?) and/or, if present, with the outer shell (14) so as in each case to support the connection part (30, 30?) on the load-bearing part (12) and, if present, on the outer shell (14).

  • Publication number: 20130097848
    Abstract: In accordance with exemplary embodiments, a system for isolating magnesium components from fastener devices is provided to prevent corrosion. The system comprises an isolation member of a metal other than magnesium and configured within a hole for receiving the fastener formed in a magnesium component. A compressible sealing washer having a first diameter is positioned over the hole and an isolation washer having a second diameter being less than the first diameter, and consisting of a similar metal as the isolation member, is placed over the compressible sealing washer. The fastener passes through the isolation washer, the compressible sealing washer and the isolation member within the hole, where is it tightened to compress the compressible sealing washer between the isolation member and isolation washer forming a water-tight seal around the hole to resist corrosion of the magnesium component.

  • Patent number: 8398350
    Abstract: A bolt has a bolt body including a screw part, a head part formed at an upper end of the screw part, and a flange part formed at a lower end of the head part; and an unconductive ring-shaped resinous member covering a peripheral portion of the flange part. The flange part has a disk-shaped flange body portion; and a seat surface-forming portion having a seat surface which is pressed against a portion where the bolt is to be mounted. The ring-shaped member has an edge part which is located at a position nearer to a lower end of the screw part than the seat surface and outward from the flange body portion and an annular skirt part whose diameter gradually increases to the edge part. The annular skirt part is so formed that it deforms when the bolt is mounted on the portion where the bolt is to be mounted and forms an annular liquid-tight sealing portion for the portion where the bolt is to be mounted.
