Cana anyone recommend a plastic wrench that doesn'e scratch the metal?


Looking for one that doesn't scratch the binding post on speaker/amp.  Looking all over the net but can't seem to find one.  Something similar to audioquest binding post wrench but plastic inside instead of metal.

It won't matter, if you have the correct size, it won't slip so it won't scratch.
Any socket will do, you just need the correct size. I used a socket many times.
Hand tight is fine.
If you have trouble with the connector holding, you may need softer connectors/spring loaded styles.

Very hard spades don't grip well.
The Audioquest wrench will allow adequate tightening with little scratching.  Used with my VAC power amp for years and the Cardas binding posts continued to look good.
