Claim 17:
18. A method for affixing substrates to one another, the method comprising:
operatively engaging a substrate defining an opening configured to receive a rivet shaft with a metal-comprising substrate defining a complementary opening;
applying a tool defining a concave profile to the rivet shaft, wherein a portion of the concave profile of the tool offset from a center of the tool engages the rivet shaft prior to the center of the tool; and
forming a stop head from the rivet shaft to affix the metal-comprising substrate to the substrate defining the opening by rotating the tool defining the concave profile to the rivet shaft and applying a force along a longitudinal axis of the rivet shaft, wherein an outer edge of the rivet shaft is engaged by the tool prior to a center of the rivet shaft; and
in response to the rotation and the applying of the force, forming a metallurgical bond between the stop head and the metal-comprising substrate.
