Any job worth doing right means having the best tools to back up your work. That's why these PRO SAE deep sockets from Fuller® Tool with 1/2-inch-drive are a standout: made from tough chrome-vanadium steel (CrV) for durability and heat treated for consistent hardness, the 6-point design ensures a snug fit each time. What's more, the chrome plate easily wipes clean and resists rust. These deep sockets are ideal for nuts on extra-long bolts that extend into the socket itself.
