The Ford Wrench is the original adjustable monkey-style wrench. This hard to find 90-degree wrench is a multipurpose addition to any well-equipped aircraft technician’s toolbox. A Ford Wrench is no simple adjustable wrench, as the 90-degree angle is often necessary to get to hydraulic, fuel, oil, and pneumatic fittings when in a spot that the open end or even angle wrench cannot get a good grip.
