We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "Bert Coules"
saying something like:

It would have been even easier though with a socket I could have used in a
drill/driver. Does such a thing exist?

That's exactly what I use on hex-head screws (the concrete fixers had
Torx heads, so it was easy enough to simply put a Torx driver in the
drill). For hex-head I have a small kit with a 1/4" drive set of
sockets, but the key piece is a hex shank to 1/4" drive tool, which
allows mounting of the sockets onto a power drill. I picked that up from
Aldi a couple of years ago and it's been dead handy for exactly this
sort of thing.
