These three way wrenches are considered "condo tools" (includes the ParkTool AWS-1), and are really made for new fasteners, nothing corroded or seized.

There's reason why you'll never see such tool by Snap On Automotive.

To remove heavily torqued or rusted fasteners, use hardened hex sockets for a 3/8" socket wrench. That's what I do.

Save the ParkTool AWS-1 for when you put lubed fasteners back on.
