Extension Bar 3/4″ Drive X 400mm (16″)

This is a 3/4″ drive extension bar, 400mm (16″) in length. It is designed to provide additional reach for socket wrenches and impact wrenches, allowing access to fasteners in recessed or obstructed locations. This tool is for professional tradespeople requiring extended leverage and access in heavy-duty applications.

What You Get

• 3/4″ square drive for compatibility with standard 3/4″ drive sockets and ratchets.
• 400mm (approximately 16 inches) overall length for extended reach.
• Single-piece construction for durability and strength under high torque.

Built For

This extension bar is built for demanding mechanical and industrial environments. It is suitable for tasks such as heavy equipment maintenance, automotive repair (trucks, buses, agricultural machinery), construction, and industrial assembly where large fasteners are common and direct access is limited. Its length is particularly useful for reaching deep-set bolts or nuts without removing adjacent components, streamlining workflow and reducing downtime.

Construction

The extension bar is constructed from steel, likely a chrome vanadium or chrome molybdenum alloy, heat-treated for strength and resistance to torsional stress. The surface features a black finish, indicative of black oxide or phosphate coating. This finish provides corrosion resistance and reduces glare, which is beneficial in various working conditions. The robust material selection and finish ensure the tool can withstand the high torque loads associated with 3/4″ drive systems and resist wear in a professional setting.
