ABSTRACT:
Dual load path fastener systems, and methods for their use, are described herein. In one embodiment, a dual load path fastener system includes first and second fasteners. The first fastener has a first end portion, a second end portion spaced apart from the first end portion, and a hole extending through the first and second end portions. The second fastener is configured to extend through the hole in the first fastener with a third end portion of the second fastener protruding beyond the first end portion of the first fastener and a fourth end portion of the second fastener protruding beyond the second end portion of the first fastener. The fastener system of this embodiment further includes a spacer portion configured to support the third end portion of the second fastener in such a way that the third end portion is longitudinally supported independently of the first fastener.
