Torque Wrench Rockforce RF-6473390 3/8" Drive, 20–120 Nm

Rockforce RF-6473390 is a 3/8" drive torque wrench with a calibration range of 20–120 Nm. Designed for controlled tightening of bolts and fasteners, this torque wrench enables repeatable torque application for automotive, mechanical and maintenance tasks. The tool is suitable for workshop and field use where adherence to specified torque values is required, providing a straightforward means to avoid over- or under-tightening.

Advantages

The wrench offers an adjustable torque scale from 20 to 120 Nm allowing one tool to cover a wide range of fastening jobs. Its 3/8" square drive is compatible with commonly used sockets, and the ratcheting mechanism simplifies operation in confined spaces. Built for accuracy and repeatability, the tool reduces the risk of damage to threaded connections and components by enabling precise torque control.

Suitable for

• Automotive repair and assembly tasks where specific torque values are required
• Mechanical maintenance and machine assembly
• Field service work and on-site equipment tightening
• Workshop general fastening tasks across a range of bolt sizes

Key specifications

• Drive size: 3/8" square drive
• Torque range: 20–120 Nm
• Adjustment: micrometer-style or scale-adjustable torque setting
• Operation: ratcheting head for reversible operation
• Typical applications: bolt and fastener tightening in automotive and mechanical contexts

How to use

Select the required torque value within the 20–120 Nm range by turning the handle to the desired setting and locking it if the wrench includes a locking mechanism. Fit a compatible 3/8" socket onto the square drive, position the socket on the fastener, and apply steady force until the wrench signals the set torque either by a click or tactile feedback. Reverse the ratchet as needed for tightening or loosening; avoid using the wrench as a breaker bar or for impact applications to maintain calibration accuracy.

Usage recommendations

Calibrate the torque wrench periodically according to frequency of use and manufacturer guidance to preserve measurement accuracy. Store the wrench at its lowest torque setting when not in use and avoid dropping or exposing it to extremes of temperature or corrosive environments. Use correct socket sizes and avoid applying side loads to maintain tool lifespan and consistent torque application.
