| 摘要 |
This invention provides a temperature responsive self-locking fastener which includes a threaded shank and a threaded mating element both having approximately equal coefficients of thermal expansion and a temperature responsive locking member having a coefficient of thermal expansion different than that of the threaded shank and the mating element. The locking member expands relative to the threaded shank and the mating element at the operating temperature to prevent disengagement of the locking fastener. At the installation temperature, the locking fastener can be easily installed or removed even after one or more cycles between the operating and the installation temperature.
