Next Richard has to remove the packing nut, which secures the stem into the faucet body. He loosens it with an adjustable wrench and pulls out the entire stem assembly with needlenosed pliers. The seat washer—a rubber disk on the stem's underside and the usual suspect in a spout drip—looks scarred, and its fastener screw is badly corroded. He's able to twist the screw off without snapping its shank, though he was prepared to drill it out and rethread the hole with his "tap and die" kit, if necessary.
