Impact Square Drive Size Adapters

Convert from one square drive size to another. These adapters are made to withstand the high torque and force of impact tools.

3/4", 1", and 1 1/2" square drive size 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.
