62599-166 ABSTRACT OF THE INVENTION A fastener for use in fatigue resistant structures such as aircraft wings. The fastener is installed into inter- ference fit by tool engagement in a tapped hole coaxial with the threaded end of the pin, at the threaded end of the fastener pin. The tapped hole is engaged by a hardened mandrel which is detachably threaded into the threaded hole in the pin. The mandrel has an extending tail end which may be gripped by a pulling tool after the threaded end of the pin is partially inserted into the workpiece with the mandrel extending through the workpiece. The tail end of the mandrel is engaged by a pulling tool that can be manually or power actuated to pull the interference fit shank into the structure workpiece to produce a fatigue resistant interference between the pin shank diameter and the workpiece hole diameter. The process results in fatigue-proofing the joint and produces the benefit of holding the pin from rotation when a threaded collar or nut is applied to the threaded end of the pin to complete the joint, installation being done without exertion of percussion forces.
