The thing about a ring spanner is that it's far less likely to slip
- and mangle the corners - than an adjustable is - specially when
you need to hit it with a hammer.

Ah, a Mole Wrench with parallel jaws. Doubtless better than a
conventional Mole wrench, or an ordinary open-ended spanner. But, at
the end of the day, it's still in effect an open-ended spanner which
only operates on two flats rather than on all six corners[1].

It works like an normal adjustable, you turn the adjuster to get the best
fit, then use the 'mole' lever to clamp it in place. Apart from giving you
an extra hand it does stop the slipping & rounding over.
