Snap-on (possibly others) also makes a wrench with a socket mounted on a hinge
on one end and an open end of the same size at the other end. Since there's
no ratchet mechanism taking up space, the socket with handle is only about
3/4" long. The hinge allows the socket part to be inserted lengthwise and
then tilted up onto the head of the bolt.
