3/8" Drive Impact Extension

The Apex UG-EX-376-4 is a 4-inch impact socket extension with a 3/8" square drive. It uses a pin retainer to hold sockets securely during high-torque applications. This hand tool is built for professional automotive and industrial maintenance tasks.

Suits mechanics needing reach in tight engine bays

Technicians who regularly work with 3/8" drive impact wrenches will find this extension adds necessary clearance. It is not for users requiring a 1/2" or 1/4" drive interface, nor for jobs needing a longer or shorter reach than four inches.

Verify your impact wrench drive size

Confirm that your impact wrench and sockets both use a 3/8" square drive before ordering. Ensure the pin retainer mechanism is compatible with your existing socket retention needs. Check that a four-inch length provides the required access for your specific fastener locations.

Questions about this item

Do I need a 3/8-inch drive impact wrench or ratchet to use this Apex UG-EX-376-4 extension?

Yes, this extension has a 3/8-inch square drive on both ends, so it requires a matching 3/8-inch drive impact wrench, ratchet, or breaker bar to operate.

Can I use this 4-inch Apex extension with my existing 3/8-inch drive impact sockets?

Yes, the 3/8-inch square drive with pin retainer accepts standard 3/8-inch drive impact sockets, allowing you to keep using your current socket set.

How can I confirm the pin retainer is holding the socket securely after I attach it?

After pushing the socket onto the extension, pull firmly on the socket; the pin retainer should lock into the socket's retention hole and prevent it from coming off during use.
