Abstract

A fastening apparatus includes a retaining member comprising a shape memory material configured to transform, responsive to application of a stimulus, from a first solid phase to a second solid phase. The retaining member is disposed within a hole in a body and secured within the hole by phase change which creates an interference fit to secure the retaining member against rotational and axial movement. The hole has a second axial cross-sectional shape. The retaining member has a first axial cross-sectional shape that is preferably either circular or rectangular.
