I'm dense so bear with me.

I have a crankset just like this one.



It has the self extracting bolts as shown. It is NOT connected to a BB spindle at the moment. The self extracting bolts are rusty and the crank is marred. I want to REMOVE the entire self extracting bolt from each arm so that I can treat the rust on the bolt and also remove the anodizing from the crank arms and polish them.

Just how do I remove the extracting bolts from the crank arm? Use a spanner and turn the ring with the two holes CLOCKWISE?

I do not have a spanner with pins small enough to fit in the bolt's holes. I would like to know where to get one. And neither I nor my LBS has a 7mm allen key.
