Zusammenfassung:A metal fastener is provided having a first threaded screw portion for engaging a complementary threaded portion of a bore of a metal member at a first temperature, and a sealing portion disposed proximal a distal end of the first screw portion, the sealing portion having a greater coefficient of thermal expansion than the metal member, wherein the sealing portion is configured to thermally expand and provide a seal between the sealing portion and an inner circumference of the bore at a second temperature higher than the first temperature, such that the first screw portion of the fastener is immobile relative to the bore at the second temperature.
