Apex 3/8" Drive Extension SAE

The Apex UG-EX-376-6 is a 6-inch socket extension built from durable alloy steel with a urethane finish. It features a 3/8-inch square male output drive and female input drive for SAE applications. A pin retainer and anti-mar covering add longevity in high-impact work environments. This single-piece tool extends wrench reach for bolts in deep or confined spaces.

Mechanics needing extra reach in tight spots

Technicians working on engines, machinery or vehicle chassis where standard sockets cannot access deep fasteners will find this extension suitable. The alloy steel construction handles high-torque demands common in professional garages. Buyers who need metric drive sizes or a different drive profile should look at other options. The fixed 6-inch length may not suit tasks requiring shorter or longer reach.

Simple attachment to compatible 3/8" tools

The extension slides onto any 3/8-inch square drive ratchet or breaker bar and accepts matching sockets without additional hardware. The pin retainer helps lock sockets in place during use. Applying excessive torque beyond the tool's design limit can damage the drive squares or shear the pin. Debris buildup under the urethane cover should be cleaned to maintain smooth engagement.

Questions about this item

What drive-size tools must I already own for the 3/8" square drive to connect?

You need 3/8" drive sockets or a 3/8" drive ratchet to use this 6-inch extension.

Will the urethane cover and pin retainer work with my older 3/8" drive sockets?

Yes, the anti-mar urethane covering and pin retainer are designed for standard 3/8" square-drive sockets.

How can I confirm the extension is seated correctly after I attach it?

The pin retainer will click into the socket's detent hole, giving a positive lock you can feel and see.
