Patent ID: 8449234

Claim:
A rivet, comprising: a hollow body having a first end, a second end, and a tube shank extending between the first end and the second end; a head flange configured at the second end of the hollow body; and a mandrel passing through the hollow body and having a first end and a second end, the first end of the mandrel coupled with the first end of the hollow body, and the second end of the mandrel having an exposed mandrel portion extending beyond the head flange a distance of a minimum of 0.25 inches to a maximum of 0.75 inches; wherein the exposed mandrel portion has a smooth surface for gripping teeth of jaws of a riveting tool to capture during rivet installation, said exposed mandrel portion being shortened to significantly reduce the cost of materials, decrease mandrel production costs, rivet assembly costs, and spent mandrel feeding and collection costs, wherein spent mandrel sliding and feeding properties through a nosepiece, split jaws, and mandrel aperture are improved when multiple components of a workpiece have either aligned or slightly unaligned workpiece holes, with optimum improved spent mandrel sliding and feeding properties existing when unaligned workpiece holes are present and a length of the exposed mandrel portion extending beyond the head flange is about-equal to or less than a length of the hollow body from the first end to the second end.
