Bahco 4040M-12-13 is a double-ended flare-nut (line) wrench sized 12 mm and 13 mm across flats, 224 mm long, for hex-head bolts and hydraulic tube fittings where an open jaw would round the fitting. The near-closed head grips five of six flats to transmit higher torque than an open-end spanner while still slipping over the tube. Made from chrome-vanadium steel.
