ABSTRACT:
The threaded split-bushing fastener assembly has been designed for high temperature applications such as on hypersonic vehicles. The fastener assembly consists of a pin (with a standard countersunk head at one end and a tapered end at the other end), a tubular threaded split-bushing, a nut, and a washer. Installation is accomplished by inserting the pin in the parts to be fastened, then slipping the washer and split-bushing on the tapered end of the pin and finally screwing the nut onto the split-bushing. Tightening of the nut allows preloading of the fastener assembly.
