Abstract: Fastening systems, fastening system installation apparatus, and methods for fastening are provided. The fastening system installation apparatus comprises a sleeve and an anvil. The sleeve comprises a first sleeve end and a second sleeve end. A sleeve cavity extends into the sleeve from the first sleeve end. The anvil is slidably received by the sleeve cavity. The anvil comprises a first anvil end, a second anvil end, and at least two portions formed by at least two channels extending from the first anvil end. The at least two portions define an anvil cavity configured to receive a fastening collar and inner surfaces of the at least two portions are configured to deform the fastening collar. The sleeve is configured to radially displace the at least two portions inward relative to the longitudinal axis responsive to forcible contact between the first anvil end and the first sleeve end.

Abstract: Non-limiting embodiments of a multi-piece fastener and a fastening method are disclosed. The multi-piece fastener comprises a fastening collar and a pin. The fastening collar comprises a first collar end, a second collar end, and an inner collar surface extending from the first collar end to the second collar end. The inner collar surface comprises a first lock region and defines a collar cavity. The pin is configured to be at least partially received by the collar cavity. The pin comprises a first pin end, a second pin end, and a shank extending intermediate the first pin end and the second pin end. The shank comprises a second lock region configured to engage the first lock region to form an interference fit between the fastening collar and the pin when the pin is received in the collar cavity. The fastening collar is configured to be deformed onto the shank.

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.
