3/8-Inch Drive Extension Bar, 75mm Chrome Vanadium Steel

Brief Overview

This 75mm extension bar is engineered for mechanics and technicians who need to reach fasteners in confined spaces without sacrificing tool integrity. The compact length makes it an essential addition to any 3/8-inch drive toolkit, particularly for engine bay work, tight corners, and precision assembly tasks. For jobs requiring greater reach, consider pairing this with a longer 150mm extension or upgrading to a flexible wobble design for angled access.

Key Features

• Chrome Vanadium Construction: Tool-grade alloy provides exceptional durability and impact resistance
• Mirror-Polished Finish: Corrosion-resistant, professional appearance with easy visibility of markings
• 3/8-Inch Square Drive: Male drive end with detent ball for positive socket retention; female receiver end with locking geometry
• Compact 75mm Length: Minimal reach extension ideal for tight engine compartments and confined work areas
• Machined Shoulders: Precision-engineered shoulders ensure accurate socket seating and alignment
• Detent Ball Retention: Prevents accidental socket separation during overhead or angled work
