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.

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.
Try making one out of a small block of maple, pear or cherry wood. It’s also a great conversation piece.
This is why I think Furutech torque guard binding posts are the Best available. Impossible to over tighten, and silly easy to tighten properly. No tools required 
@zavato agree but seems an overkill solution to change the binding post completely for not wanting to scratch it lol
