If you mean the thin washers on the "EZ" connectors then yes, one goes on the "EZ" connector, then stick the threaded portion through the servo arm, and then the other washer, then the nut. I have found for some reason, that I usually am not able to use both due to the thickness of the servo control arms. Sometimes, I will use one, or none depending on the thickness of the servo arm. Be VERY careful when putting the CA glue on the nut after you have it adjusted for the proper movement, as it is very easy to glue the "EZ" connector to the servo arm.
