Abstract: Rivet dispenser reloading systems and methods of use thereof are provided. A non-limiting embodiment of a rivet dispenser reloading system comprises a receiving member defining a channel therein, and a first gate. The rivet receiving member comprises a first port and a second port that communicate with the channel. The first port is configured to receive rivets. The second port is configured to selectively engage with a rivet dispenser and introduce rivets to the rivet dispenser. The channel extends between the first port and the second port and is configured to transport rivets from the first port to the second port in a series arrangement and in a preselected orientation. The first gate is in communication with the second port and is selectively positionable between a first configuration inhibiting movement of rivets through the second port, and a second configuration enabling movement of rivets through the second port.

Abstract: Blind fasteners and methods of fastening are provided. A blind fastener comprises a sleeve and a mandrel. The sleeve is adapted for installation into a threaded bore in a structure. The sleeve comprises a head portion configured to receive a torque, a first sleeve end, a second sleeve end, an elongate portion extending intermediate the first sleeve end and the second sleeve end, and a cavity extending from the first sleeve end to the second sleeve end. The mandrel is at least partially disposed through the cavity of the sleeve. The mandrel comprises a first mandrel end disposed adjacent to the first sleeve end. The first mandrel end comprises an enlarged portion having a diameter greater than a diameter of the cavity. The elongate portion is configured to at least partially deform into threads of the threaded bore responsive to forcible contact between the enlarged portion and the sleeve.

Abstract: A fastener includes a sleeve, a core bolt and an insert. The sleeve includes a tubular portion and an internal thread. The core bolt includes a cylindrical portion, a threaded portion with an external thread, and a thread runout between the cylindrical portion and the threaded portion. The core bolt is disposed within the sleeve and the external thread engages the internal thread. The insert is disposed within the sleeve and encircles a portion of the core bolt. The insert abuts and is retained between the internal thread and the thread runout in a pre-installation position. The insert is compressed between the internal thread and the thread runout by an installation motion of the core bolt simultaneously with a generation of a compressive load on the sleeve. The insert deforms simultaneously with and facilitates a formation of a bulb in the sleeve in response to the compression.
