Our SAE 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.
