Wrench adapter/extension YATO YT-01670, 170 mm length, 1 pc

The YATO YT-01670 wrench adapter/extension is a 170 mm single-piece extension designed to increase the working reach of sockets and ratchets. It permits access to recessed or hard-to-reach fasteners in automotive repair, machinery maintenance and general workshop tasks where additional length is necessary for tightening or loosening bolts.

Advantages

This extension is made from chrome vanadium (CrV) steel and features a matte chrome-plated surface that provides corrosion resistance and a durable finish. The 170 mm length gives improved reach without sacrificing control, and the single-piece design ensures straightforward connection to compatible sockets and ratchets. The adapter is intended to fit standard square drive tools and extends accessibility to recessed fasteners while maintaining torque transfer.

Suitable for

• Automotive repair and service where recessed nuts and bolts are present
• Machinery maintenance and industrial equipment servicing
• General workshop tasks requiring additional reach for tightening or loosening fasteners
• Situations where a stable, rigid extension is needed to transmit torque

Key specifications

• Length: 170 mm
• Material: chrome vanadium (CrV) steel
• Surface finish: matte chrome plating
• Designed for use with sockets and standard square drive ratchets

How to use

Attach the adapter to the square drive of a compatible ratchet or wrench, then connect the desired socket to the opposite end. Ensure the connections are fully seated before applying torque. Use steady, controlled force when tightening or loosening fasteners and avoid sudden impacts that could damage the adapter or connected tools. After use, wipe the extension clean and store in a dry place to protect the matte chrome finish.

Usage recommendations

Use the YATO YT-01670 extension with sockets and ratchets that match the square drive size; do not use with tools or sockets that show excessive wear or damage. Do not apply the adapter beyond recommended torque for the connected socket or fastener type. Regularly inspect for visible wear, deformation or corrosion and replace if any structural damage is found.
