Extension Bar AWTools 1/4" 100 mm Black Line AW38147BL

The AWTools 1/4" 100 mm Extension Bar Black Line is a tool accessory designed to extend the reach of 1/4" drive sockets. With a length of 100 mm and a protective Black Line finish, it enables access to fasteners located in recessed or confined spaces while maintaining compatibility with standard 1/4" drive ratchets and torque tools. The solid construction provides a straight, rigid connection between ratchet and socket, helping to transfer torque effectively for routine automotive, mechanical and maintenance work.

Advantages

The 100 mm length increases reach without adding excessive flex, allowing easier engagement with recessed nuts and bolts. The Black Line protective finish reduces surface corrosion and wear, preserving fit and function over time. Precision-machined connections ensure a secure fit to 1/4" drive sockets and ratchets, minimising play and improving torque transmission. The compact size keeps the tool easy to position in tight workspaces and to store with other hand tools.

Suitable for

• Automotive repair where sockets must reach recessed fasteners
• Mechanical assembly and disassembly in confined areas
• General maintenance and household repairs requiring deeper socket reach
• Use with 1/4" drive ratchets, torque wrenches and socket sets

Key specifications

• Drive size: 1/4" compatible
• Length: 100 mm effective reach
• Finish: protective Black Line coating
• Material: hardened tool steel (standard for extension bars)
• Connection type: square male/female 1/4" interface

How to use

Select the appropriate 1/4" drive socket and attach it to the extension bar's female end. Connect the extension bar's male square to a compatible 1/4" drive ratchet or torque wrench. Insert the socket over the fastener and apply turning force using the ratchet or torque tool as required. For torque-controlled operations, be aware that using an extension bar can affect torque accuracy; follow equipment guidelines when precise torque values are required.

Usage recommendations

Inspect the extension bar before use for signs of wear or damage. Use within the rated capacity of your hand tools; avoid impact tools unless the extension bar is specifically rated for impact use. Store in a dry place to preserve the Black Line finish and protect against corrosion.
