Tie down assembly

A tie down assembly (10) including a cup (12), a cross-shaped crossbar (14) that is fastened removably to and positioned within a recess (36) of the cup (12), and a discshaped plate (16) that is fastened removably to the cup (12) and/or the crossbar (14). The crossbar (14) is fastened to the cup (12) by a plurality of fasteners (18), while the plate (16) is fastened to the cup (12) and/or the crossbar (14) by at least one fastener (18). The cup (12) is installed within a hole formed within a first surface (94) of a structure (92), and the plate (16) is positioned against an opposite surface (96) of the structure (92). When the plate (16) is attached, a compressive load is introduced and squeezes the first and second surfaces (94, 96) of the structure (92) together, such that most of the load is borne down the center of the fastener (18) attaching the plate (12).
