  • Bolt/stud and nut for enhanced high-cycle fatigue capability
    Patent number: 5779416
    Abstract: The bolt or stud shaft and nut combination includes an undercut of the first thread of the shaft adjacent the load face of the nut, the undercut having a compound fillet with the smaller radius lying between the larger radius and the first thread of the shaft. The shaft threads are buried two threads deep into the nut so that the first two teeth of the nut do not contact the threads of the shaft and overlie the undercut. The nut threads have a taper opening the pitch diameter in a direction towards the loaded face. The combination affords resistance to high-cycle fatigue of rotating structures joined together by the bolt or stud shaft and nut combination.
