This is a 19mm metric crowfoot wrench with a 3/8-inch square drive, forged from alloy steel and full-polished. The open jaw grips four flats of the fastener while leaving one side clear, which is what lets it work on a nut with a line running through it.
It suits larger hydraulic and fuel fittings, suspension hardware, and fasteners set behind other components. On an extension it keeps a torque wrench aligned where a socket simply will not go.
Wright Tool has forged hand tools in Barberton, Ohio since 1927, using no foreign blanks and only U.S. steel.
