• Industrial maintenance where square-drive sockets of size 9×12 mm are used
• General workshop work including machinery servicing and component installation

Key specifications

• Drive type: square drive
• Drive size: 9×12 mm
• Finish: black
• Intended use: controlled torque application for fastening
• Typical applications: automotive, industrial maintenance, workshop assembly

How to use

Select a compatible 9×12 mm square-drive socket and attach it securely to the torque wrench. Set the required torque according to the fastener or vehicle manufacturer’s specification using the tool’s adjustment mechanism, then apply force steadily until the set torque value is reached. Maintain a perpendicular alignment between wrench and fastener to avoid side loading, and handle the wrench with consistent motion to achieve accurate results. After use, store the tool in a dry place to protect the finish and mechanism.

Usage recommendations

Regularly check the calibration and condition of the torque wrench to ensure ongoing accuracy. Use sockets and extensions that are compatible with the 9×12 mm square drive and avoid applying impact forces or using the tool as a breaker bar. Follow manufacturer torque specifications for fasteners and perform routine inspections of the tool for signs of wear.
