Impact Hex Bit Sockets

These sockets are made to withstand the high torque and force of impact tools.

3/4" and 1” square drive size sockets 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.
