  • Patent number: 10259973
    Abstract: The anti-corrosion coating material contains corrosion inhibiting inorganic constituents, or a combination of inorganic and organic corrosion inhibiting constituents, suspended in a polymeric resin. The corrosion resistant composition includes a salt of inorganic constituents, and alkaline polyamine fatty acid salt (PFAS) as a corrosion inhibitor, suspended in a polymeric resin remainder. The coating material may be applied to metal parts but not limited to aircraft fasteners, such as aircraft fastener parts, including nuts and bolts, screws, rivets, and sleeved systems.

  • Patent number: 9027216
    Abstract: A swage collar and an internal sealing insert form a swage collar assembly used in combination with a structural fastener to prevent leakage through a connection of workpieces fastened together by the structural fastener. The swage collar has a hollow, generally cylindrical main body portion with a main central bore, and a base portion with an internal shoulder formed in the main central bore so as to form a seal receiving guide. The shaft of the fastener typically includes a threaded section and an unthreaded section, and the internal sealing insert interfaces with the threaded section and the unthreaded section of the shaft of the pin. In an alternate embodiment, the internal sealing insert interfaces with the unthreaded section of shaft of the pin.

  • Patent number: 8118527
    Abstract: A fastener for installation into a workpiece which may be installed by either a swaging operation or a torquing operation. The fastener includes an enlarged protruding head which is proximal to a substantially cylindrical smooth shank portion. A threaded shank portion positioned distal to the smooth shank portion includes a male thread which is sufficiently strong to have a swage collar swaged onto it. Distal to the threaded shank portion is a pin tail portion having a surface which is configured to engage a tool. Positioned between the threaded shank portion and the pin tail portion is a breakneck groove having a lower tensile strength than any other portion of the fastener. The tensile strength of the breakneck groove is controlled such that the fastener severs within the breakneck groove when a preset range of tension is applied to the pin tail portion by the tool.

  • Publication number: 20090285653
    Abstract: A drive socket for a male threaded fastener includes three rounded lobes of equal radius which are located equidistant from the center of the fastener and 120° apart from each other. The drive socket also includes three flat surfaces, each flat surface being located opposite one of the lobes and equidistant from the center of the fastener. Another embodiment of a drive socket includes a first set of three lobes and a second set of three lobes, each lobe being of equal radius and equidistant from the center of the fastener. The lobes of the first set are 120° apart and the lobes of the second set are also 120° apart and 60° apart from the lobes of the first set. Each of the lobes of the first set includes a flat surface which is adjacent and tangential to the radius portion of the lobe.

  • Publication number: 20080226414
    Abstract: A threaded insert for providing stronger threads to a parent material. The threaded insert includes a bushing portion having male threads on the external surface and female threads within an internal bore. The threaded insert also includes keys which lock the threaded insert into a threaded hole within the parent material. The keys are positioned within slots along the external surface of the bushing portion of the threaded insert. The slots include two substantially parallel walls which are substantially perpendicular to a bottom surface of the slots. A method for assembling the threaded insert reduces the tendency of the keys to be installed offset from the bottom surface of the slots.
