Abstract
A rivet for joining a plurality of structural members having a cylindrical shank and a head with a conical undersurface, flared uniformly outwardly from the shank, an upper surface that is generally similar to the minor portion of a filled torus, sliced normal to its centerline and an outer edge therebetween which is rounded adjacent the conical undersurface and cylindrical adjacent the upper surface. When being installed in a workpiece aperture to form a joint, the rivet head coldflows to assume adequate expansion into the aperture while becoming generally flush to the workpiece surface so rivet head shaving is not required.
