QB Digital Torque Wrench
QB Digital Torque Wrench
Precision Torque Control for Critical Fastening
The Fanyaa QB Digital Torque Wrench is designed for controlled fastening, torque verification and assembly quality management. With torque ranges from 0.5 to 1000 N·m, it combines preset torque settings, TRACK, PEAK and PRE operating modes, sound and LED alerts, 999-record storage and optional Bluetooth transmission.
Reduce Fastening Errors with Controlled Torque
Incorrect torque can affect joint reliability, product quality and assembly safety. Under-tightening may result in loose fasteners, while excessive torque can damage bolts, threads or components. The QB Digital Torque Wrench gives operators real-time torque readings and clear target alerts, helping reduce guesswork during critical fastening tasks.
Designed for Efficient Daily Torque Work
High-Accuracy Torque Measurement
Available in ±1% or ±2% accuracy configurations for different assembly and quality-control requirements.
Preset Torque Setting
Set the required target torque before operation to create a more consistent fastening process.
Sound and LED Alerts
Audible and visual alerts help operators identify when the preset torque has been reached.
Backlit Digital Display
The clear LCD screen provides easy torque-value visibility in workshops and low-light environments.
Reversible Ratchet Head
The ratchet direction can be switched for different fastening and operational requirements.
Ergonomic Handle
The shaped handle provides a comfortable and stable grip during repeated torque operations.
Three Operating Modes for Different Torque TasksTRACK Mode
Displays the applied torque value continuously in real time.
PEAK Mode
Captures and displays the maximum torque value reached during operation.
PRE Mode
Allows the operator to set a target torque and receive sound and LED alerts when approaching or reaching the preset value.
Five Selectable Torque Units
The QB Digital Torque Wrench supports N·m, lbf·ft, lbf·in, kgf·cm and kgf·m, making it suitable for different engineering standards and international applications.
