Abstract
A self-drilling blind rivet includes a deformable sleeve and a shaft having a drill bit at one end. The shaft extends through the sleeve and the drill bit is connected to one end of the sleeve. The shaft and sleeve are rotatable as a unit. A method for making a riveted joint with a self-drilling blind rivet includes the steps of passing the drill bit through a work piece and pulling the drill bit entirely within the sleeve so that the drill bit does not extend beyond the end of the sleeve to which it is connected. Thus, the diameter of a portion of the sleeve in increased and the riveted joint is rendered pressure tight.
