ABSTRACT:
A blind setting rivet slidingly joined to a rivet installation tool for rotation therewith for drilling the rivet through walls, panels or components of a member. The rivet includes a shank threadingly joined to a sleeve thereon, the shank having a drilling bit on a forward end thereof. The sleeve has an enlarged flange on a rear end thereof to prevent the sleeve from passing entirely out through the hole formed in the walls, panels or components, and also to prevent the sleeve from rotating upon engagement with the walls, panels or components when the shank is rotated by the tool, thus causing the drilling bit to deform the forward end of the sleeve to form an enlarged collar to capture the sleeve within the hole formed in the walls, panels or components by the drilling bit, where the sleeve joins the walls, panels or components together. The tool has a non-circular opening to receive a non-circular mandrel section of the shank so that the tool can rotate the shank. Preferably, the tool includes a magnet to releasably secure the mandrel section therein, and a spring to eject a broken-off rear shank portion format the tool once the sleeve is deformed. The tool is adapted to be received in a conventional electric drill for rotation thereof.
