Abstract
A two-part fastener for an assembly having a sealed joint formed by at least two flanges or sealing surfaces. A first flange defines a first opening, a second flange defines a second opening with a seal being disposed between the first and second flanges. The flanges and seal are secured together with a bolt and a receiver that defines a threaded hole for receiving the bolt. The receiver includes an end face engaging the first flange and a shoulder engaging the second flange. The spacing between the end face and the shoulder defines a gap for the seal. The shoulder of the receiver may include a weld bead that is welded to the second flange. In one embodiment, three flanges are assembled together with a seal between each flange.
