A family of rivets including both blind and bucked-type rivets made at least partially from an amorphous metal alloy. A blind rivet includes a head portion and a tail portion. At least one of the head portion and the tail portion is configured to elastically deform to secure a first member in position relative to a second member. The head portion and the tail portion may include one or more deformable legs having an interface feature configured to engage with one of the first member and the second member. A bucked-type rivet assembly includes a formable member and an anvil. The anvil is configured to thermoplastically deform the formable member proximate to the second member by passing current through an electrical circuit that includes at least one of the formable member and anvil.

The fastener includes a bolt, a nut, a sleeve, and a drive nut. The drive nut interfaces with the nut. The bolt is disposed through the nut, sleeve, and drive nut. The bolt comprises one or more threaded portions and a non-threaded portion. The fastener breaks-off at the non-threaded portion during installation. The installed fastener comprises a recess-free, flush surface with a workpiece.

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.

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.

Disclosed is a fastener that includes a nut with a threaded bore that includes a head on one end having three recesses, a cylindrical outer surface and a tapered ramp on the other end, a bolt that includes a head, a threaded portion engaged with the threaded bore, a recess next to the bolt head and an enlarged shank between the threads and the recess, where the outer diameter of the recess is smaller than a major diameter of the threaded bore of the nut and where an outer diameter of the shank is larger than a major diameter of the bolt threads, and a sleeve with a unthreaded bore positioned between the tapered ramp and the bolt head with one end crimped into the recess such that the internal diameter of the crimped sleeve bore is smaller than the major diameter of the threads on the bolt.

A blind tacking rivet includes a stem and a sleeve. The stem includes a body and a stem head. The stem head is removable from the body. The stem head deforms a portion of the sleeve during removal of the stem head. The stem head may be discarded or may be embedded within the sleeve.

A tool for installing a blind fastener including a core bolt and a core nut is provided. The tool includes a driving member, a collet driven by the driving member for engaging the core bolt, and an external sleeve for holding the core nut and preventing the core nut from rotating during installation of the blind fastener. The external sleeve is movable between a first position in which the external sleeve is driven by the collet to rotate with the collet and a second position in which the external sleeve is stationary despite rotating action of the collet.

A blind fastener for connecting panels includes a bolt and nut. The bolt includes a shaft, bolt head, and lug. The bolt head is between the shaft and lug. The shaft defines external threads opposite the bolt head. The lug includes a first tool engagement portion and first frangible portion that connects the lug and bolt head. The nut includes a sleeve, nut head, and handling member. A central bore of the sleeve receives the shaft and defines internal threads mated with the external threads. The nut head is between the handling member and sleeve. The nut head extends radially from the sleeve and defines a recess that receives the bolt head. The handling member surrounds a portion of the lug. The handling member includes a second frangible portion and a second tool engagement portion. The second frangible portion couples the second tool engagement portion to the nut head.

A blind fastener for connecting a plurality of panels includes a core bolt and a core nut. The core nut surrounds the core bolt. The core nut includes a main body, a nut head, and a tool engagement section. The nut head has a larger outside diameter than the main body. The core nut defines a frangible portion between the nut head and the tool engagement section. The frangible portion is configured to allow the tool engagement section to break off from the nut head when a torque applied to the tool engagement section is greater than a threshold torque after the blind fastener is installed in the plurality of panels.

Disclosed is a fastener that includes a nut with a threaded bore that includes a head on one end, a cylindrical outer surface and a tapered ramp on the other end, a bolt that includes a head, a threaded portion engaged with the threaded bore, a recess next to the bolt head and an enlarged shank between the threads and the recess, where the outer diameter of the recess is smaller than a major diameter of the threaded bore of the nut and where an outer diameter of the shank is larger than a major diameter of the bolt threads, and a sleeve with a unthreaded bore positioned between the tapered ramp and the bolt head with one end crimped into the recess such that the internal diameter of the crimped sleeve bore is smaller than the major diameter of the threads on the bolt.
