Torque wrench Wiha 2859 9 mm 140 Nm, adjustable click-type torque tool

The Wiha 2859 torque wrench with a 9 mm drive and 140 Nm maximum torque is a precision adjustable click-type tool designed to apply a predefined torque to fasteners. It provides an audible and tactile click when the set torque is reached, enabling consistent, repeatable tightening for maintenance, assembly, and mechanical service tasks. The tool's construction is intended for professional environments where controlled torque application and reliability are required.

Advantages

The adjustable click mechanism allows accurate setting of torque values and delivers a clear, repeatable confirmation at the target torque. The compact 9 mm drive supports accessibility in tighter workspaces compared with larger drives, while the 140 Nm capacity covers a broad range of medium- to high-torque applications. The torque wrench is built for durability and frequent use, offering stable calibration retention and a simple adjustment interface for quick changes on the job.

How to use

Select the required torque value using the adjustment mechanism or calibrated scale and lock the setting according to the tool's locking feature. Place the appropriate socket or accessory on the 9 mm drive, position the wrench squarely on the fastener, and apply smooth steady force. When the preset torque is reached, the wrench will produce a distinct click and a tactile release; stop applying force immediately to avoid over-torquing. After use, return the setting to the lowest torque or the tool's recommended storage position to help maintain calibration.

Recommendations

Use the torque wrench only for its intended purpose on correctly sized fasteners and sockets. Periodically verify calibration according to the frequency recommended for professional tools or after any suspected impact or drop. Store the tool in a dry, clean environment and avoid using it as a breaker bar or for loosening fasteners beyond its design intent.
