It is a precision tool that can preset the target torque value and has sound or tactile prompts, used to control the tightening torque of threaded fasteners such as bolts and nuts. When the applied torque reaches the preset value, the wrench will prompt the user to stop applying force through a "click" sound, hand vibration or mechanical lock to avoid thread damage or tightening failure due to overload. Its core function is to accurately control the torque to ensure the reliability and consistency of the threaded connection.

Preset function: By adjusting the handle scale line, the target torque value can be quickly set, and the main and auxiliary scales can be fine-tuned together.

Double prompt: When the preset value is reached, the wrench will make a "click" sound, accompanied by obvious hand vibration to prevent overload.

Accuracy range: Clockwise/counterclockwise operation accuracy can reach ±3% (20%-100% of the range)

Excellent repeatability: Alloy steel material and precision structure design, guaranteed for 5,000 times or one year of use, and can still maintain stable performance after long-term use.

Two-way operation: The clockwise/counterclockwise force direction can be switched through the ratchet steering switch, suitable for different working conditions.

Ergonomics: The handle provides a comfortable grip and reduces hand fatigue

Accessory compatibility: Can be used with ER/UM

Sturdy material: Made of chrome-plated alloy steel or high-strength alloy forging, it is impact-resistant, wear-resistant and has a long service life.

Protective design: The metal shell is anti-collision, the laser scale is clear and wear-resistant, and some models have anti-rust treatment.

Industry coverage: automobile manufacturing, aerospace, shipbuilding, electricity, precision instruments and other fields, especially suitable for high-precision assembly scenarios such as engines and bridge bolts.
