ABSTRACT:
A metal rivet, a two-piece rivet assembly, and a joint including the assembly. The metal rivet includes a preformed head at one end of a solid shank. At the other end there is a tubular upsettable portion which is circularly cylindrical with a recess which terminates at a base opening at said other end of the solid shank. The tubular upsettable portion is so proportioned as to form a proper upset head. At least a part of a core pin fits in the tubular upsettable portion and is retained therein after the rivet is set. During setting it prevents internal buckling of the tubular upsettable portion, and after setting it reinforces the upset head to prevent rollout as a consequence of axial separative forces. As an optional feature, at the terminal part of the forming of the upset head, the core pin can be pressed against the base to swell the solid shank and create a closer, or even an interference, fit for the shank in a workpiece.
