Actually, I think most sockets and box-end wrenches are like this to
some degree, but with rounded rather than squared openings. I suppose
it depends on to what extent this is true and to the closeness of the
flat opening tolerance that determines the likelihood that a tool will
round-off a bolt or nut.
BTW, Bonney is still around. I bought a Bonney torque wrench recently
and saw them at a number of different places. In fact, I was told by
the owner of one local auto parts store that he often has them on sale.
One other interesting thing about Bonney is that at one time they made
Whitworth wrenches. I have one that I bought around 1969. Who knows,
maybe they still do make them.
