Choose the Correct Fit
Match the input to a 1-inch square-drive impact wrench. Check that the socket uses the specified output drive size.
Seat the 1-1/2-inch drive socket fully on the output and check the ball detent. Secure the input using the tool’s retaining arrangement.
Installation & Care
Keep the tool, adapter and socket aligned. Follow the limits for every part of the setup; a drive-size change does not create additional torque capacity.
Inspect both square-drive interfaces and the retention features. Replace a cracked, distorted or loose-fitting adapter before use.

Important Product Questions
Is this a socket for a bolt head?
No. It changes a 1-inch square drive to a 1-1/2-inch square drive. A separate impact socket fits the fastener.
Can it be used in reverse?
Select an adapter with the correct input and output for the tool and socket. This model’s input is 1 inch; the specified output faces the socket.
Does it change the tool’s torque rating?
No. Use the tool, adapter and socket within their own limits. This listing does not state a numeric torque capacity for the adapter.
