The Lisle Corporation 7-pc Offset Filter Wrench Set, No. 40600, is designed for use on oil and fuel filter canisters when replacing the element. The set features a low profile, 6-point wrench with an offset 3/8" square drive for clearance in hard-to-reach spaces. The size is laser marked on each wrench and the set comes in a blow molded case for storage. If using a torque wrench with these adapters, adjust the torque setting to compensate for any change in length between the center line of the fastener and the center line of the torque wrench drive. The torque setting will be the same if the offset wrench is at 90 degrees to the handle of the torque wrench.
