EXTENSION BAR 3/4″ DRIVE X 100MM (4″)

This is a 3/4″ drive extension bar, 100mm (4 inches) in length. It is designed to provide additional reach for sockets and other 3/4″ drive accessories, allowing access to fasteners in recessed or obstructed areas. This tool is for professional tradespeople requiring reliable extension for high-torque applications.

What You Get

• 3/4″ Drive Compatibility: Ensures fitment with standard 3/4″ drive ratchets, breaker bars, and impact wrenches.
• 100mm (4″) Length: Provides a practical extension for reaching fasteners without excessive leverage or interference.
• Secure Socket Retention: Features a detent ball for positive socket engagement and retention during use.

Built For

This extension bar is built for heavy-duty mechanical work, industrial maintenance, and automotive repair where 3/4″ drive tools are standard. It is suitable for breaking loose stubborn fasteners, reaching engine components, chassis bolts, or industrial machinery where direct access is limited. Its robust design is intended for consistent use in demanding environments.

Construction

The extension bar is constructed from steel, likely chrome vanadium or chrome molybdenum alloy, given its intended application with 3/4″ drive tools. The surface features a black finish, indicative of black oxide or phosphate treatment. This finish provides a degree of corrosion resistance and reduces glare. The material and finish suggest it is engineered for high-stress applications, including use with impact tools, although specific impact rating is not stated.
