This 15-piece 1/2″ (12.7 mm) deep impact socket set is designed for impact wrenches. The sockets have thicker walls and carry higher torque, making it easy to loosen high-strength fasteners. All sockets are forged and precision heat-treated, with a black rust-proof oxidation surface, and are stored in a red ABS portable box. They are both durable and easy to carry.
