Torque Adapter Wiha 29701200S4 1/4" drive, torque range 2–10 Nm

The Wiha Torque Adapter 29701200S4 is a precision torque-limiting adapter for 1/4" drive tools, offering a controlled torque range of 2–10 Nm. Designed to transfer a preset torque from a driver to fasteners, this compact adapter helps ensure consistent tightening without requiring a full-size torque wrench. Its compatibility with standard 1/4" sockets and bits makes it suitable for a variety of assembly, maintenance and repair tasks where preventing over- or under-tightening is important.

Advantages

The adapter provides accurate torque limiting within a narrow 2–10 Nm range, reducing the risk of damage to components and fasteners. Its compact construction allows access in confined spaces while maintaining repeatable torque application. Built to integrate with standard 1/4" drive tools and bits, it simplifies workflow by converting common drivers into controlled-torque tools without altering the hand tool set. The simple mechanical design requires no batteries or calibration equipment for typical on-site use.

Suitable for

• Electronics assembly and repair
• Precision mechanical assembly (small machinery, instruments)
• Automotive and bicycle maintenance of small fasteners
• Maintenance tasks where controlled torque prevents thread or component damage

Key specifications

• Drive size: 1/4" (compatible with standard 1/4" sockets and bits)
• Torque range: 2–10 Nm
• Function: torque-limiting adapter for repeatable tightening
• Construction: compact mechanical adapter suitable for confined spaces

How to use

Attach the Wiha torque adapter to a 1/4" drive tool or ratchet, then fit the appropriate 1/4" socket or bit. Set the required torque within the 2–10 Nm range according to the fastener and manufacturer specifications, then apply steady force until the adapter clicks or limits rotation, indicating the preset torque has been reached. When the adapter activates, stop applying force and reposition as needed. Regular visual inspection for wear is recommended to ensure consistent performance.

Usage recommendations

Use the adapter with compatible 1/4" drivers and fasteners within the specified torque range. Consult component or fastener manufacturer torque specifications before use. Avoid applying impulsive or excessive force beyond the rated range, and periodically inspect the adapter for signs of wear or damage to maintain accuracy.
