Choose the Correct Fit
Match the 1/2 in drive at the tool and socket. Use impact-rated components throughout the assembly.
Isolate the powered tool before fitting parts. Fully engage every connection and confirm the retention mechanism holds.
Installation & Care
Choose the shortest practical reach. Support the tool in line with the socket and keep hands clear of rotating parts.
Inspect the drive corners, retention features and body for damage. Replace a cracked or distorted accessory before use.

Important Product Questions
Can I use this with an impact wrench?
Yes. This SHOCKWAVE accessory is designed for 1/2 in drive impact wrenches and impact sockets. Verify that the complete assembly is impact rated.
How do I select the reach?
Use the shortest extension that provides socket, tool and hand clearance. Avoid stacking extra connections when one suitable extension reaches the fastener.
Does an extension increase tightening torque?
It provides access, not a higher torque rating. Follow the fastener procedure and verify final torque with an appropriate torque-measuring tool.
