    Flex Impact Socket Extensions

    Image of Product. Front orientation. Contains Inset. Socket Extensions. Flex Impact Socket Extensions.
    Attach one of these extensions to your impact socket to turn fasteners in hard-to-reach spaces. The flex head pivots to access fasteners from an angle. Made of one integrated extension and flex adapter rather than two pieces, the design lowers the risk of an adapter falling as you reach into your workspace. These extensions are sturdy enough to withstand the high torque and force of impact tools.
    These extensions require a locking retainer. Use with an impact wrench that has a pin-style socket retainer, or use a socket retaining ring with tools that have a hole- or hole-and-ring style socket retainer.
