The Milwaukee 16 mm metric combination wrench gets 25% more torque than smooth faced wrenches with its MAXBITE open end grip. In addition to providing increased torque, MAXBITE reduces rounding and stripping of nuts and bolts. This wrench is built from the ground up with an I-beam handle for optimized comfort and durability. Ink-filled size labels allow for easy size identification and quick-distinction between SAE and metric sets. The Milwaukee 16 mm combination wrench features a lifetime guarantee.
