SKU CH-3GXT-JYEEV

  • Extends reach for deep or confined fasteners
  • 3-inch overall length adds needed clearance
  • 3/8-inch square drive fits compatible sockets
  • Alloy steel construction withstands impact-rated work
  • Urethane finish with anti-mar cover resists wear

Apex 3/8" Drive Extension Overview

The Apex UG-EX-376-3 is a 3/8 inch drive extension built for SAE fasteners. It adds three inches of reach so mechanics and technicians can access bolts in deep or confined spaces. The alloy steel construction and urethane finish handle impact-rated work conditions.

Upgrade from shorter or worn extensions

Replace shorter extensions when the fastener sits deeper than your current reach allows. Switch from a damaged or non-impact extension when the job demands impact-rated durability and the anti-mar covering protects surrounding surfaces. The pin retainer adds secure socket retention during heavy use.

Simple square-drive installation

Connect the female 3/8" square input to your ratchet or breaker bar and the male 3/8" square output to the socket. The pin retainer locks the socket in place without extra tools. Ensure the drive sizes match your existing 3/8" drive set; this extension will not fit 1/4" or 1/2" drive tools.

Questions about this item

Will the 3 inch overall length clear my 3/8" drive ratchet in tight engine bays?

The extension measures 3 inches overall and both the input and output drives are 3/8" square, so it adds only that length between the ratchet and socket.

How do I attach the extension to my ratchet and socket without the pin falling out?

Align the female square drive on the extension with the male square on your ratchet, push until the pin retainer clicks into the detent, then fit the socket onto the male square output the same way.

How often should I replace the urethane anti-mar covering if it gets gouged?

Inspect the urethane cover before each use; replace the extension once the covering is torn enough to expose the alloy steel underneath.
