The Milwaukee Tool Flex Head Ratcheting Combination Wrenches feature a flexible head design that allows better access in hard-to-reach spaces. With 2.5 degree of arc swing and 144 ratcheting positions, the wrenches allow for quick and efficient work in tight and awkward spaces. The double-stacked pawls within the ratcheting mechanism are engineered to increase durability and extend the life of the tool. The Max Bite open-end grip improves the wrench’s grip on nuts and bolts and the ergonomic I-beam handles offer comfort in high torque situations. The ink-filled size labels provide easy size identification and are color-coded for quick distinction between SAE and metric sets.
