Key Features and Benefits
1. Unmatched Precision Control
At the heart of this torque wrench lies an advanced digital sensor that continuously monitors applied force. With a torque range of 3.7 to 37 ft.lb (5 to 50 Nm) and a professional-grade accuracy of ±2%, you can confidently tighten fasteners to exact specifications. The real-time torque readings are displayed on the high-definition LED screen, ensuring you stay in complete control.
2. Triple Alert System
Prevent overtightening with the triple alert system, which provides instant feedback when your preset torque value is reached. The wrench alerts you through:
- Vibration
- LED Indicator
-
Audible Buzzer
These three signals work together to ensure precise tightening without any guesswork.
3. Durable and Reliable Construction
Constructed from premium chrome-vanadium steel, the wrench undergoes a six-stage heat treatment for superior durability. The chrome-plated mirror finish not only enhances its professional appearance but also resists rust and corrosion, ensuring longevity even in demanding environments.

4. Multiple Operating Modes
Customize your workflow with three versatile modes:
-
Real-Time Tracking Mode: Monitor torque as you apply force.
-
Peak Hold Mode: Record the highest torque value applied for reference.
-
Preset Memory Mode: Store and recall frequently used torque settings for repeated tasks.
These modes make it easy to adapt the wrench to various projects, enhancing both precision and efficiency.
5. Compact Design for Tight Spaces
The 72-tooth ratchet with a 5° rotation requirement ensures smooth operation, even in tight and confined spaces. The one-click socket release mechanism allows for quick and effortless socket changes, saving you time and hassle.
