Extension Bar AWTools 1/4" 75 mm Black Line (AW38146BL)

AWTools 1/4" 75 mm extension bar from the Black Line series is a compact steel socket extension designed to increase reach for 1/4-inch drive sockets. It provides an additional 75 mm of length between a ratchet and socket, allowing access to recessed or hard-to-reach fasteners without changing the drive tool. The matte black finish reduces glare and helps resist surface wear in workshop environments.

Advantages

The extension bar offers precise fit and reliable torque transfer thanks to machined square ends and tight dimensional tolerances. Its 75 mm length strikes a balance between added reach and tool control, making it practical for confined spaces. The durable steel construction and treated surface provide resistance to corrosion and everyday abrasion, while compatibility with standard 1/4" ratchets and sockets ensures straightforward integration with existing tool sets.

Suitable for

• Automotive repair in tight engine bays and underbody areas
• Maintenance and equipment servicing where recessed bolts or nuts occur
• Assembly lines and production tasks requiring repeatable access to fasteners
• Home workshop use for furniture, appliances, and DIY projects

Key specifications

• Drive size: 1/4 inch
• Length: 75 mm
• Material: steel with protective black finish
• Connection type: machined square drive ends for ratchet and socket engagement
• Surface treatment: anti-corrosion black coating

How to use

Attach the extension bar to a compatible 1/4" drive ratchet or handle by pushing the square end into the ratchet drive until it clicks or seats securely. Fit the desired 1/4" socket onto the opposite end of the extension. Use the assembly to reach recessed fasteners, applying torque smoothly and avoiding sudden impacts. After use, wipe clean of grease or debris and store with other drive tools to prevent loss.

Usage recommendations

Use the extension bar only with 1/4" drive sockets and ratchets; avoid using with impact drivers or air tools not rated for hand-drive extensions. For high-torque applications, select appropriate-length extensions and consider using a torque-limiting tool to prevent overloading the extension bar. Regularly inspect for wear or deformation and replace if any damage is observed.
