Gearwrench's High-Strength Wheel Protector Impact Socket Set, No. 84946, lasts three times longer than other thin wall sockets, according to the company. The sockets have a high-strength reinforcing ring that increases durability and provides added strength, while protecting lugnuts on a vehicle from getting marred. The unique socket design helps to provide access in confined spaces and the color-coded outer jacket helps to easily identify the socket size. The sockets also feature a manganese phosphate coating, which offers two times the life of black oxide coatings, further enhancing the socket's durability. The three-piece set comes in a durable blow-molded storage case.
