A hidden tie down provides a round collar that is inserted into a like-sized round aperture formed in a planar surface. A cap and cap mount are attachable to the collar at the outer face of the surface. A fastener secures the collar to the surface at the inner face of the surface. Two opposing bushings are disposed within the collar to retain each end of a hook loop within them. The hook loop includes a round lid that closes off a like-sized round opening in the cap such that, in one position, the lid closes off the cap opening and creates a substantially flush surface across the cap. In another position, the hook loop extends outwardly from the cap opening to provide an attachment structure. Each bushing includes a detent to retain the hook loop in a stowed position.
