Tolsen ½” x 10″ Extension Bar

Tolsen ½” x 10″ Extension Bar

The Tolsen ½” x 10″ Extension Bar (Item No. 15128) is an essential precision tool for any professional mechanic’s arsenal, specifically engineered to overcome the challenges of reaching fasteners in cramped or deep-seated environments. At 250 mm (10 inches) in length, this extension bar bridges the gap 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 material selection ensures that the tool can handle significant torque loads while remaining highly resistant to the corrosion and wear common in busy workshop environments. The design includes a knurled band on the shaft, which provides a non-slip surface for rapid hand-spinning of fasteners before final tightening with a ratchet. Whether you are performing a complex engine rebuild or routine industrial maintenance, Tolsen’s industrial-grade construction provides the reliability and precision needed for professional results.

Key Benefits:

• Maximum Versatility: The 10-inch length is ideal for reaching through engine bays or deep into industrial assemblies.

• Exceptional Durability: The CrV steel construction prevents the bar from twisting or snapping under high-pressure mechanical tasks.

• Improved Workflow: The knurled grip allows for faster removal and installation of fasteners by hand.

• Secure Connection: Precision-engineered drive ends ensure a tight fit with sockets and ratchets, reducing the risk of tool slippage.

Perfect For:

• Automotive Repair: Accessing spark plugs, manifold bolts, and suspension components.

• Industrial Plants: Maintaining machinery where fasteners are often located behind safety guards or deep within the unit.

• Heavy Duty Maintenance: Ideal for use with the Tolsen 18″ Power Handle when extra reach and high leverage are required simultaneously.

Application Instructions:

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

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

3. Guide the socket onto the recessed fastener.

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

5. Use the knurled section of the bar to spin loose fasteners quickly by hand.

Pro Tips:

• Torque Precision: For critical fasteners, use this extension with the Tolsen 1/2″ Torque Wrench to ensure you reach exact manufacturer specifications.

• Rusted Bolts: If a bolt is seized, apply Selsil Pro Rust Remover first to reduce the risk of stripping the fastener while using the extension.

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