EXTENSION BAR 3/8″ DRIVE X 450MM ( 18″)

This is a 3/8″ drive extension bar, 450mm (18 inches) in length, designed to provide extended reach in mechanical and fabrication applications. It is intended for professional tradespeople requiring reliable access to fasteners in confined or recessed areas where standard socket wrenches cannot reach directly.

What You Get

• 3/8″ square drive male and female ends
• 450mm (18″) overall length
• Solid bar construction

Built For

This extension bar is built for automotive technicians, industrial mechanics, maintenance engineers, and general tradespeople working with 3/8″ drive socket systems. It facilitates access to engine bay components, machinery assemblies, plumbing fixtures, and structural elements where obstructions prevent direct tool engagement. Its length is particularly useful for deep-set fasteners or those requiring significant clearance from the work surface.

Construction

The extension bar is constructed from steel, indicated by its robust, solid form. The primary finish is black, suggesting a black oxide coating or similar treatment. This finish provides a degree of corrosion resistance and a non-reflective, low-sheen appearance. The surface texture appears to be a matte or satin finish, consistent with professional-grade hand tools. The 3/8″ square drive ends are precisely machined to ensure a secure fit with sockets and drive tools, minimizing play and maximizing torque transfer. The overall design prioritizes strength and durability under typical workshop conditions.
