ABSTRACT:
A self-heading stud and screw rivet fastener with an elongated shank having a socket at one end, a threaded portion adjacent the socket end, an enlarged head secured to or formed on its other end, and a central reduced diameter portion. A tubular sleeve and a washer providing a radial flange at one end of the sleeve are positioned around the reduced diameter portion of the shank. Preferably, the washer and sleeve are a one-piece annulus. The diameter of the sleeve through bore is less than either the enlarged head or the threaded portion of the shank so that the annulus is centrally entrapped on the shank. By inserting the fastener into a hole in a workpiece, using the socket to hold the shank from rotation, and tightening a nut engaging the threaded portion of the shank, the enlarged head is drawn toward and into the annulus to deform it and secure the fastener to the workpiece.
