The MILWAUKEE® 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. Milwaukee 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. MILWAUKEE® 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 an ergonomic I-Beam handle designed for improved comfort and ink-filled size labels for easy size identification and quick distinction between SAE and metric sets. MILWAUKEE® combination wrenches feature Milwaukee's lifetime guarantee.
