The Milwaukee 15-Piece Metric Flex Head Ratcheting Combination Wrench Set features 2.5° of arc swing and 144 ratcheting positions， allowing quick and efficient work in tight spaces. The flex head wrenches have double-stacked pawls within the ratcheting mechanism， which increases durability and extends the life of the tools. The flexible head gives users increased accessibility in difficult-to-reach areas. The MAXBITE Open-End Grip improves the wrench's grip on nuts and bolts， offering users 25% more torque than smooth-faced wrenches. This flex head wrench set feature 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. The 15-piece ratcheting combination wrench set comes in a tray designed for steel storage drawers for efficient storage with no wasted space. Milwaukee combination wrenches feature a lifetime guarantee. The Milwaukee hook and pick set features an all-metal core for up to 50% more durability. Chrome-plated shanks reduce corrosion and provide superior rust protection. A comfort grip handle and precision knurling increase tool control and user comfort. Finally， the kit comes in an easy-access storage tray for long-term tool storage. This kit includes 15 flex-head wrenches and a 4-piece hook/pick set.
