That's almost exactly what I was trying to find. Does the end of the handle have a square hole to use a ratchet at the end for adding torque?

I put the tool on my tool wish list; I'm noticing no socket end so I would probably cut some flats into the little metal cap at the handle end so I can use a wrench.
