The STEELMAN 42775 5-Piece 3/8-Inch Drive Low Profile Oil Filter Socket Set is designed to help remove the caps on canister type oil and fuel filters used on a variety of vehicle makes and models. Made from durable chrome-vanadium steel, these compact sockets average 1.5-inches in height making them ideal for engine compartments with little room to maneuver larger sockets. Designed to fit any 3/8-inch drive ratchet or wrench, these tools are not intended for impact use as the additional strain can damage canister caps. Each socket has a black phosphate protective coating to protect them against rust and corrosion. With five sizes to choose from including 24mm, 27mm, 29mm, 32mm, and 36mm, this set has a socket to fit oil and some fuel filter canister caps used by the following vehicle manufacturers: Mercedes-Benz, Ford, Renault, Nissan, Dodge, Hyundai, Mini, Fiat, Kia, BMW, Audi, Saab, GM, Saturn, Pontiac, Chevrolet, and more. A convenient molded black plastic storage case is included with the set for easy organization and transport.
