Package Content: The crowfoot wrench set includes 15 crowfoot wrenches - 8mm to 18mm for 3/8-inch drive and 19mm to 24mm for 1/2-inch drive. All these wrenches are packed inside a storage case for your convenience. Function: The crowsfoot wrench set includes 15 metric crowfoot flare nut wrenches for 3/8inch and 1/2inch drive ratchet, extension, or torque. It also comes with a 15 size claw adapter to extend the range of common wrenches. This set allows you to reach awkward angles and hard-to-reach areas that regular sockets or wrenches cannot. Extended Range: The crowfoot adapter extends the reach of a standard wrench to inaccessible fasteners in tight spaces. Once in place, your existing ratchet, extender, or torque wrench can easily attach to the crowfoot drive hole and drive the fasteners. They are fully compatible with your existing metric 38 and 12 drive tools, meeting all your needs. High Quality: Made of industrial-grade, heat-treated, drop chrome steel, this crows foot wrench set ensures maximum torque and against rust. The return tabs at the jaws offer better leverage and grip, and they slide easily over your fasteners., Weight: 3.26063685498 pounds, Manufacturer: Awwertse
