Continuous-Use Square Drive Size Adapters

These adapters, which convert from one square drive size to another, were designed to tolerate continuous use with impact tools in high-volume production and assembly. They’re hardened to resist cracking and wear from repeated use, lasting longer than standard impact adapters.

3/4" Square Drive and 1" Square Drive—_3/4" and 1" square drive size adapters 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.

Impact Magnetic Square Drive Size Adapters

A magnet holds the socket, making changes quicker. These adapters convert from one square-drive size to another. They’re sturdier and have more give than manual-drive adapters, so they'll withstand the high torque and force of impact tools.

3/4" Square Drive—Adapter with _3/4" square drive requires a retaining ring on the female end for attachment to tools that have a hole- or hole-and-ring style socket retainer.

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.
