Abstract
The tapered split-bushing fastener has been designed for high temperature applications. The fastener consists of a pin (with a standard countersunk head at one end and a tapered end at the other end), a split tapered bushing, a washer and a sleeve with an internal taper. Installation is accomplished by inserting the pin in the parts to be fastened, then slipping the washer and the split bushing on the tapered end and finally pushing the sleeve onto the split bushing. Pushing the sleeve causes the split-bushing to react against the washer and generate the fastener axial preload. A high temperature adhesive is then injected to lock the fastener in place.
