A fastener adapted to be installed in a hole of a composite structure includes a sleeve, a pin member, and a locking member. The sleeve has an outer surface having an outer diameter. The outer surface of the sleeve is textured. The outer diameter of the tubular portion is less than an inner diameter of the hole of the structure. The pin member has a shank portion. 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.

A fastening method for fastening using a fastener having a fastener pin and a collar. The method includes a mounting step in which, in a state in which a head portion of the fastener pin is positioned on one side of the portion to be fastened through which the fastener pin is passed, and a lock portion of the fastener pin is positioned on the other side of the portion to be fastened, the collar is mounted onto lock grooves. The method includes a fastening step in which, on the basis of an un-swaged portion height derived from the thickness of the portion to be fastened, the collar is swaged onto the lock grooves and the portion to be fastened is fastened.

A fastening system includes a plurality of fasteners having different sizes, and is provided with a pressurizing pump which pressurizes a fluid to a prescribed pressure, a plurality of pressurizing units which each have a pressure receiving surface, are each disposed in a position capable of pressurizing each respective fastener, and which receive the fluid on the pressure receiving surface to pressurize each fastener. A supply system includes a base end connected to the pressurizing pump and a plurality of branch ends connected to each pressurizing unit, which branches from the base end toward the branch ends, and which is capable of supplying the fluid from the base end throughout the branch ends. Each pressure receiving surface has an individual pressure receiving surface area corresponding to the corresponding size, and the fluid is supplied at the prescribed pressure from the base end throughout the pressure receiving surfaces.

A fastener assembly for use with one or more workpieces. The fastener assembly can be a single-sided (i.e., blind) fastener assembly in which the fastener assembly is inaccessible from one side of the workpiece(s). In this regard, the workpiece(s) can make-up an enclosed component, for example. The fastener assembly can have a fastening end, such as a threaded stud, for securement with a distinct component that is otherwise detached from the fastener assembly. The workpiece(s) can be composed of a carbon fiber composite material, an aluminum material, or another type of material.

A swaged fastener (10) includes a coated collar (12) for location in use on a pin (14). In an unswaged condition, the coated collar (12) comprises a substrate material (16) having a substrate colour and an indicator material (20) having an indicator colour. The indicator material (20) is located on the substrate material (16). The indicator colour is visually different to the substrate colour. The coated collar (12) includes a swaging surface (18) to which, in use, a swaging force is applied to move the collar (12) from the unswaged condition to a swaged condition. The indicator material (20) comprises at least part of the swaging surface (18) and is arranged so that, in a correctly swaged condition, the indicator material (20) comprising the swaging surface (18) is substantially removed to expose the substrate colour and thereby provide a visual indication that the swaging process has been correctly carried out.

A lockbolt swage end effector incorporates a swage tool engaged by a connector assembly to a frame. The frame is attached to a robotic manipulator. A jaw assembly is supported on a mounting assembly, the jaw assembly having opposing articulating jaws forming a recess to engage a collar in a closed position in alignment with a swage puller and die in the swage tool. The articulating jaws release the collar in an open position for operation of the swage tool.
