Our 7 Piece Metric Flex Head Ratcheting Combination Wrench Set features 2.5 degrees 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 you increased accessibility in difficult-to-reach areas. The 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 set 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. The 7pc kits come in a portable, locking storage tray, offering organization both on and off the jobsite. Standing behind our products, we offer a Lifetime Guarantee on all of our Combination Wrench Sets.
