Tool name question

I need a wrench to grip a smooth ring that has a row of holes 'round its circumference. I know what the tool looks like, but can't search for it without knowing the proper name for it. Anyone know?
Thanks

Do you mean a tool or socket similar to what would be used to take off a grinding wheel?

thing looks much like a question mark. I'm supplying myself with three days cooked rations before turning to the search engine, since I shall likely be there for some time to come.

Hi:

There are two basic types of wrench for this application, as you may have holes or square notches or slots- the first is for the holes or notches on the outside surface of the nut (circumference, as you described), in which case the tool is a handle with a curved arm, the end of which has a pin for a round hole or a square boss for a slot. The second would be for holes or slots in the face of the nut, and the wrench would consist of a handle with a "C" shaped pair of arms with either pins for holes or square bosses for slots.

These wrenches may have pivot pins where the arm(s) meet the handle in order for the wrench to adjust to a limited range of different-sized nuts.

Take a look at this web site:

The wrenches they show for holes around the outside of the nut are called "hook wrenches". For those with holes on the surface of the nut, they refer to them as "pin wrenches".

In engineering in the UK (there are a few factories left) we call them 'C' spanners. Most lathes have a locking ring behind the chuck that holds it onto onto the headstock spindle and a 'C' spanner is the bit of kit that tightens it up. I assume that in the US it is called the same thing except it may be called a 'c' wrench. Mark Twains 2 countries seperated by a common language!
