EXTENSION BAR 3/8″ DRIVE X 250MM (10″)

The EXTENSION BAR 3/8″ DRIVE X 250MM (10″) is a precision-machined accessory designed to provide essential reach in confined or obstructed work areas. It extends the effective length of your 3/8″ drive ratchet or breaker bar, allowing socket access to fasteners that are otherwise out of reach due to depth or surrounding components. This tool is for professional tradespeople requiring reliable, consistent performance in demanding mechanical and assembly tasks.

What You Get

• 3/8″ square drive male and female ends for universal compatibility with 3/8″ drive sockets and ratchets.
• 250mm (approximately 10 inches) overall length, providing significant extension without excessive flex.
• Positive ball detent on the male drive end for secure socket retention.
• Knurled band for improved grip during manual handling or when starting fasteners.

Built For

This extension bar is engineered for applications in automotive repair, industrial maintenance, heavy equipment servicing, and general mechanical assembly where standard socket wrench setups lack the necessary reach. It is suitable for breaking loose stubborn fasteners, tightening to specified torque values in recessed areas, and accessing engine bays, chassis components, or machinery with restricted access points.

Construction

This extension bar is constructed from high-strength alloy steel, likely chrome vanadium (Cr-V) or chrome molybdenum (Cr-Mo), for superior torque transmission and resistance to twisting or fracturing under load. The dark, non-reflective black finish is consistent with a black oxide or phosphate coating, providing enhanced corrosion resistance and a reduced visual signature in industrial environments. The precise machining of the square drive ends ensures a snug fit with minimal play, crucial for preventing rounding of fasteners and maintaining torque accuracy.
