Extension bar YATO YT-1340, chrome vanadium steel, 19 mm socket, 100 mm length, 1 pc

YATO YT-1340 is a 3/4" drive socket extension with a length of 100 mm designed to extend the reach of 3/4" drive sockets. It creates a rigid link between a ratchet or breaker bar and the socket, allowing access to recessed or hard-to-reach fasteners commonly encountered in automotive repair, industrial maintenance and general mechanical work. The solid construction ensures torque transfer while preserving alignment between tool and fastener.

Advantages

The extension offers a compact 100 mm length that balances reach and control, reducing the risk of wobble during torque application. Its 3/4" drive interface is compatible with a wide range of heavy-duty sockets and drive tools, enabling use with ratchets, torque wrenches and breaker bars. Built for repeated professional use, the extension provides a secure fit and reliable torque transmission without introducing significant play.

Suitable for

• Automotive engine and chassis work where bolts are recessed
• Industrial machinery maintenance and assembly tasks
• Heavy-duty mechanical repairs requiring 3/4" drive tools
• Workshop and professional service use

Key specifications

• Drive size: 3/4"
• Length: 100 mm
• Type: rigid socket extension
• Primary application: extend reach to recessed fasteners
• Compatibility: designed for use with 3/4" drive sockets and compatible drive tools

How to use

Select a 3/4" drive socket appropriate for the fastener, attach it securely to the extension, then connect the extension to the ratchet, torque wrench or breaker bar. Insert the socket onto the fastener and apply torque as required, maintaining alignment between tool and fastener. For removal tasks, ensure the extension and socket are fully engaged before applying reverse torque. After use, wipe the extension clean and store in a tool chest or holder to prevent corrosion and damage.

Usage recommendations

Use the extension with compatible 3/4" sockets and tools rated for the required torque. Avoid excessive side load or using the extension as a lever; if more reach or flexibility is needed, consider a longer extension or a swivel/impact-rated accessory. Inspect the connection points regularly for wear and replace the extension if any deformation or rounded corners appear.
