ABSTRACT:
A metal blind rivet assembly having a plurality of ribs with flutes between them located about the circumference of the barrel of the rivet sleeve. The ribs are arranged in a helix and at an angle so that during the setting operation a twisting motion takes place to scrape the workpiece so that contaminants such as dirt or varnish are removed to provide electrical contact with the workpiece.
