Abstract
An enhanced fatigue nut for mating with a threaded mating component includes an exterior surface, a flanged mating end for insertion of a threaded mating component and an end opposing the flanged mating end. Disposed on the interior of the fastener may be a plurality of threads running from the flanged mating end toward the opposing end. The flanged mating end may have a load distributing profile that reduces a limiting stress on the threads of the mating component when the mating component is mated with the enhanced fatigue nut. The flanged mating end may have an end surface, a portion of which is disposed at an angular relationship with a line that is disposed perpendicular with a line that is disposed through the center of the interior of the enhanced fatigue nut. This angled portion creates a gap between the enhanced fatigue nut and another component, such as a washer, so that when the enhanced fatigue nut is mated with the mating component, the enhanced fatigue nut can bend or deflect into the gap and thereby shift the loads on the mating component to reduce the peak limiting stress on the threads of the mating component. This thereby increases the fatigue life of the mating c…
