Patent number: 10457414Abstract: A fastener including a sleeve having an elongated portion, a head with a bearing surface, and an internal threaded portion, a core bolt disposed within the sleeve and having a head and a shank portion having an external threaded portion engageable threadedly with the threaded portion of the sleeve. An insert is disposed within the sleeve and surrounds a portion of the core bolt. A seal element is attached to the sleeve and juxtaposed with the bearing surface of the head of the sleeve. The fastener is adapted to be installed in a structure. The electrical contact of the fastener reduces the potential difference between it and the structure, which provides a direct path for continuous propagation of electromagnetic waves, reducing electromagnetic wave scattering and minimizing the electromagnetic signature.Type: GrantFiled: December 8, 2017Date of Patent: October 29, 2019Assignee: Arconic Inc.Inventors: Andreas Liebscher, Wudhidham Prachumsri, Curtis Lea, Luke Haylock

Publication number: 20180163766Abstract: A fastener including a core bolt and a sleeve adapted to receive the core bolt. The sleeve includes an elongated portion and a head including a first, outer surface and a plurality of embossments located on and extending from the first surface. The plurality of embossments is adapted to mate with and be engaged by corresponding debossments of a fastener installation tool. The embossments react installation torque.Type: ApplicationFiled: December 5, 2017Publication date: June 14, 2018Applicant: ARCONIC INC.Inventors: Luke Haylock, Wudhidham Prachumsri, Curtis Lea

Publication number: 20180154626Abstract: A component including a wall with a first surface, a second surface opposite the first surface, and at least one aperture formed within the wall and extending from the first surface to the second surface. At least one boss is located on the first surface of the wall and around the at least one aperture, the at least one boss being constructed by layered, additive manufacturing. Optionally, the aperture need not be included. A method including the steps of providing a component having a wall with a first surface, a second surface opposite the first surface, and at least one aperture formed within the wall and extends from the first surface to the second surface thereof, and constructing at least one boss on the first surface of the wall of the component and around the at least one aperture using layered, additive manufacturing.Type: ApplicationFiled: December 1, 2017Publication date: June 7, 2018Applicant: ARCONIC INC.Inventors: Luke Haylock, Manish Kamal, Rodrigo Pinheiro, Wudhidham Prachumsri, Adam Travis

Patent number: 9939004Abstract: A pin member for a fastener includes an elongated shank having a first end, a second end opposite the first end, a cylindrical shank portion having an outer surface, a head located at the first end of the elongated shank, the head including a bearing surface located on the bearing surface of the head, and a threaded portion located at the second end of the elongated shank. The pin member can be fully coated with a coating. A conformable seal element is attached to the pin member, which is adapted to fill the microscopic voids between the bearing surface of the head of the pin member and the surrounding structure under the axial load exerted by the fastener during installation. The seal element can be separate and distinct from the pin member. The seal element can be attached to the pin member for the sake of convenience, but the seal element can deform independently of the pin member and the surrounding structure in response to the forces exerted by the fastener.Type: GrantFiled: March 3, 2016Date of Patent: April 10, 2018Assignee: ARCONIC INCInventors: Manish Kamal, Luke Haylock, Hasim Mulazimoglu, Andreas Liebscher, Gregory Rizza, Rodrigo Pinheiro, Wudhidham Prachumsri
