I've seen them, played with one.  The power companies here use their 
hydraulic auger to turn the thimble eye, and expand these.  They drill 
the hole, then press the thimble eye with this on the end into the 
bottom, then rotate the rod to expand the anchor, using an "impact" 
setting on the hydraulic motor.  It sounds like a jackhammer as it 
rotates.  I watched them install one on the edge of my land one day.

I played with one, greased it up so the petals would slip, couldn't turn 
it enough, even with levers, sledge hammers, even a truck couldn't open 
it up.

I THINK, the threaded portion is on the inside/bottom, so wouldn't work 
reversed, as a cup in the hole, without the risk of the "nut" popping 
loose from the inside and the anchor slipping out.
