Our Metric Flex Head Ratcheting Combination Wrenches feature 2.5 degrees of arc swing and 144 ratcheting positions, allowing quick and efficient work in tight spaces. Our flex head ratcheting wrenches have double-stacked pawls within the ratcheting mechanism, which increases durability and extends the life of the tools. The flexible head gives you increased accessibility in difficult-to-reach areas. Our MAXBITE™ Open-End Grip improves the wrench's grip on nuts and bolts, offering you 25% more torque than smooth-faced wrenches. This flex head wrench features ergonomic I-Beam handles designed for improved comfort and ink-filled size labels for easy size identification and quick distinction between SAE and metric sets. MILWAUKEE® combination wrenches are backed by our lifetime guarantee.
