EXTENSION BAR 1/4″ DRIVE X 150MM ( 6″)

This 1/4″ drive x 150mm (6″) extension bar is a fundamental component for professional tradespeople requiring extended reach in confined or obstructed workspaces. It is designed to bridge the gap between a 1/4″ drive ratchet or power tool and a socket, enabling access to fasteners that are otherwise out of reach.

What You Get

• 1/4″ square drive male end for socket attachment.
• 1/4″ square drive female end for ratchet or power tool connection.
• 150mm (approximately 6 inches) overall length for moderate extension.
• Knurled mid-section for enhanced grip during manual manipulation or when oil/grease is present.
• Ball detent on the male drive end for secure socket retention.
• Through-hole on the female drive end for positive retention with corresponding drive tools.

Built For

This extension bar is built for applications requiring precise fastener access in tight engine bays, under dashboards, within machinery enclosures, or any scenario where a direct connection to a fastener is impeded by surrounding components. It is suitable for mechanics, electricians, maintenance technicians, and assembly line workers who frequently encounter recessed fasteners.

Construction

The extension bar features a dark gray to black industrial finish, consistent with manganese phosphate or black oxide coatings, providing corrosion resistance and reduced glare. The material appears to be a hardened alloy steel, offering the necessary tensile strength and torque resistance for professional use. The knurling is deeply cut, indicating a manufacturing process designed for durability and consistent grip. The male drive end incorporates a spring-loaded ball detent, while the female end includes a precisely machined through-hole, both critical for reliable socket and drive tool retention under load.
