For the pep boys tool, CTA 2036, I use one of the Pittsburgh 67011 square socket caps. This allows an open wrench to be used, but as soon as you crack it loose, you have to remove the tool due to clearance issues. It really only used to break it loose and tighten it.

Question: does anyone know whether the Snap on socket (PMM408A) allows a normal socket wrench to be used? Or do you need to get a thin wrench with that socket as well?
