A system includes a housing of a wellhead, a hanger configured to be positioned within the housing of the wellhead, and a hanger retention system. The hanger retention system includes a key-slot interface having at least one retention segment configured to move between a collapsed position in which the at least one retention segment does not block movement of the hanger relative to the housing of the wellhead and an engaged position in which the at least one retention segment engages at least one corresponding slot to block movement of the hanger relative to the housing of the wellhead. The at least one retention segment includes a wavy cross-sectional shape at least while the at least one retention segment is in the engaged position that enables the at least one retention segment to move between the collapsed position and the engaged position.
