1/4-Inch Drive Extension Bar, 150mm Length, Chrome Vanadium

Brief Overview

This 150mm extension bar is a foundational accessory for any 1/4-inch drive socket set. Constructed from chrome vanadium alloy, it provides reliable reach for fastening work in confined or recessed spaces. The spring-loaded detent ball on the square male drive end securely retains sockets during use, minimizing dropped fasteners and improving workflow efficiency. For shops requiring extended reach capabilities, this standard length pairs well with longer extension options or articulated alternatives to cover a wider range of applications.

Key Features

• Chrome Vanadium Construction: Stamped alloy marking confirms material composition; provides strength and corrosion resistance for durability in workshop environments
• Spring-Loaded Detent Ball: Positive socket retention prevents accidental disconnection and reduces job-site frustration
• Polished Chrome Finish: Mirror-quality surface enhances visibility and resists corrosion
• 150mm Working Length: Ideal mid-range reach for general fastening and assembly tasks without excessive leverage complications
• Square Male Drive (1/4" Drive): Standard SAE drive interface compatible with all 1/4-inch drive sockets and accessories

Business Advantages for Resellers

• Bundling with socket sets to increase perceived value
• Repeat sales to workshops expanding tool collections
• Margin-friendly pricing due to simple manufacturing and high demand
• Stock stability with minimal obsolescence risk
