Abstract: Rivet dispenser systems and methods of use thereof are provided. In a non-limiting embodiment, the rivet dispenser system comprises a rivet receiving member defining a channel therein, and a seat member. The channel includes a curved region. The rivet receiving member comprises a first port and a second port. The first port communicates with the channel and is configured to receive rivets. The second port communicates with the channel and is configured to dispense rivets. 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 seat member communicates with the second port and is configured to selectively engage with a rivet holder of a resistance spot rivet welding apparatus and introduce a single rivet to the rivet holder at one time.

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.
