ABSTRACT:
A riveted joint employing a rivet having a cylindrical shank and a head with a conical undersurface, flared uniformly outwardly from the shank and truncated by an upper surface that is generally similar to the minor portion of a filled torus, sliced normal to its centerline. When being installed in a workpiece aperture to form the joint, the rivet head cold-flows to assume adequate expansion into the aperture while becoming generally flush to the workpiece surface so rivet head shaving is not required.
