Title: FASTENER SYSTEM WITH EXPANDABLE RING
Abstract:
A fastener system is provided that includes a spindle bolt having a threaded section and a tooling interface at a head, a bolt body at least partially mated with the spindle bolt, including an anti-rotation slot and an outer surface, a nut including an interior threaded portion and an anti-rotation extension, and an expandable ring mated with the nut and including a lower clamping surface. In a clamping configuration of the fastener system, the lower clamping surface extends beyond the outer surface of the bolt body, the interior threaded portion of the nut is threadingly engaged with the threaded section of the spindle bolt, and the anti-rotation extension mates with the anti-rotation slot. In an installation configuration of the fastener system, a diameter of the lower clamping surface is less than a diameter of the lower clamping surface in the clamping configuration.
