Abstract
A threaded fastener includes an outer body defining an axis and an inner body at least partially positioned within the outer body. The inner body is movable along the axis relative to the outer body. A plurality of threaded segments is coupled to the outer body and radially supported by the inner body. The plurality of threaded segments defines a nominal diameter. At least one biasing member biases the plurality of threaded segments inward toward the axis. The plurality of threaded segments is movable inward toward the axis by the at least one biasing member when the inner body is moved axially from a first position to a second position so that the plurality of threaded segments define a reduced diameter that is smaller than the nominal diameter.
