an outlet communicating with the first channel and configured to dispense rivets,
wherein the first channel extends between the inlet and the outlet and is configured to transport rivets from the inlet to the outlet;
a seat member communicating with the outlet and 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, wherein the seat member comprises a first jaw, a second jaw, and a block structure to receive a rivet from the second port and maintain the rivet in a preselected position and orientation; and
an actuation member configured to move a rivet located within the seat member to a secondary position located above the seat member; and
(ii) the rivet holder comprising a collet assembly, the collet assembly comprising an actuator and a collet connected to the actuator, the collet assembly being adapted to be installed on an external electrode holder, the collet being moveable by the actuator from an advanced position, in which the collet is adapted to grip a rivet, and a retracted position, in which at least a portion of the collet is retracted into the actuator to enable an electrode attached to the electrode holder to engage the rivet.
