ABSTRACT:
A sealing fastener, such as a sealing rivet, is disclosed for sealing engagement with a workpiece. The sealing fastener has a head and a shank extending from a lower surface of the head. An aperture passes through the head and shank, and a mandrel and collar fit within the aperture. A sealing member, such as an O-ring is disposed between the collar and the mandrel. The head of the sealing fastener may also have a groove formed therein and may have a sealing member disposed at least in part in the groove. In use, the rivet is placed through an opening in the workpiece, and a lower portion of the shank is collapsed so to form a lower head and so that the upper and lower heads engage the workpiece. The sealing member is compressed between the collar and a wall of the aperture, and the collar and mandrel are placed in locking engagement to maintain the sealing member in a compressed state.
