Tolsen ½” x 5″ Extension Bar

Tolsen ½” x 5″ Extension Bar

The Tolsen ½” x 5″ Extension Bar (Item No. 15127) is a fundamental precision tool for any professional mechanic, specifically engineered to provide access to fasteners in cramped or recessed environments. At 125 mm (5 inches) in length, this extension bar acts as a bridge between your ratchet and the workpiece, allowing for efficient torque delivery in spaces where a standard tool configuration would be obstructed.

Crafted to rigorous industrial standards, this extension bar is forged from polished Chrome Vanadium (CrV) steel. This high-performance material ensures that the tool can withstand significant torque loads while remaining highly resistant to the corrosion and chemical exposure common in busy workshop settings. The design includes a knurled band on the shaft, providing a non-slip surface for rapid hand-spinning of fasteners before final tightening. Whether you are performing a complex engine repair or routine industrial maintenance, Tolsen’s industrial-grade construction provides the reliability and precision needed for professional results.

Key Benefits:

• Optimized Access: The 5-inch length is ideal for bridging medium-depth gaps in engine bays or industrial assemblies.

• Exceptional Durability: The CrV steel construction prevents the bar from twisting or snapping under heavy industrial pressure.

• Faster Workflow: The knurled grip allows for more efficient removal and installation of fasteners by hand once they are loosened.

• Precise Connection: Precision-engineered drive ends ensure a secure fit with sockets and ratchets, minimizing tool slippage.

Perfect For:

• Automotive Maintenance: Accessing manifold bolts, suspension components, and engine mounts.

• Industrial Plants: Maintaining machinery where fasteners are recessed behind guards or specialized components.

• Professional Mechanics: An essential staple for any high-torque, 1/2″ drive tool collection.

Application Instructions:

1. Connect the female end of the extension bar onto your 1/2″ drive ratchet or breaker bar until it clicks securely into place.

2. Snap the desired 1/2″ drive socket onto the male end of the extension.

3. Guide the socket directly onto the recessed fastener.

4. Apply steady pressure to tighten or loosen as required.

5. Use the knurled section of the bar to rapidly spin fasteners by hand when they are loose.

Pro Tips:

• Combine for Reach: For even deeper access, this 5-inch bar can be combined with a Tolsen 10″ Extension Bar to navigate complex mechanical assemblies.

• Flexibility for Angles: Pair this extension with the Tolsen 1/2″ Universal Joint to reach fasteners at awkward angles.

• Tool Care: Wipe the extension bar with a clean, slightly oily cloth after use to maintain the polished CrV finish and prevent oxidation.
