The sleeve is adapted to expand radially over the shank portion of the pin member to form an interference fit between the outer surface of the sleeve and the hole of the structure so as to provide an installed position of the fastener. When the fastener is in the installed position, the texture of the outer surface of the tubular portion deforms to engage with voids of the composite material present on the inner surface of the hole.
High strength forged aluminum alloys and methods for producing the same are disclosed. The forged aluminum alloy products may have grains having a high aspect ratio in at least two planes, generally the L-ST and the LT-ST planes. The forged aluminum alloy products may also have a high amount of texture. The forged products may realize increased strength relative to conventionally prepared forged products of comparable product form, composition and temper.

Fastener installation tool with internal concentric sleeves
A fastener installation tool including a cylinder assembly having a housing and a handle/sleeve assembly attached to the housing. The handle/sleeve assembly includes a handle having a bore and an inner wall defined by the bore. The handle/sleeve assembly further includes an outer sleeve having an outer wall and an inner wall, and an inner sleeve having an outer wall and an inner wall. The outer sleeve is positioned within the bore of the handle, while the inner sleeve is positioned concentrically within the outer sleeve to form an annular space between the outer wall of the inner sleeve and the inner wall of the outer sleeve. The annular space is utilized to conduct hydraulic fluid.
A wheel for a pneumatic tire has a rim with one monolithic bead seat and a removable beat seat. The removable bead seat has two halves that embrace the rim and engage a groove to retain the tire. The removable bead seat may have a second lip either monolithically formed or as a part of a separate retainer that bolts to the bead seat. The wheel may be made from aluminum alloy.
An apparatus and method for fastening dissimilar materials like steel, plastic and aluminum. A resistance welding fastener having multiple layers may be used with or without a sealant. The fastener may be used to form an aluminum covered steel laminate via a hemming pattern of attachment. The fastener may have a solid shaft or have an extended reach and have features for interacting with the welding electrode. A variety of electrode tips may be employed to cooperate with the fastener.

A fastening system including a fastener and a fastener installation tool. The fastener includes a pin member having an elongated shank portion with a threaded portion, a stop shoulder located at an end of the threaded portion, and a pull portion extending from the stop shoulder. The stop shoulder includes an inner annular wall extending longitudinally from the end of the threaded portion, and an inner face extending outwardly and obliquely from the shank portion. The inner annular wall and the inner face form an annular receiving area. The fastener installation tool includes a puller having a front face. The receiving area of the fastener is adapted to receive the front face of the fastener installation tool when the puller engages the pull portion of the pin member.
