Product Information
Full details
This Laser Tools Insulated Torque Wrench is designed for professionals working on hybrid and electric vehicles, offering precise torque application up to 25Nm with 1000V AC / 1500V DC insulation for live working safety. Its key benefit is enabling safe and accurate tightening of critical components in high-voltage systems, though its specific torque range makes it less suitable for heavy-duty applications requiring higher torque values. It features a clear scale, easy adjustment mechanism, and VDE certification.

FAQs
What is the primary advantage of this torque wrench for EV work?
Its primary advantage is the IEC60900 standard insulation, allowing for safe operation on live electrical systems up to 1000V AC / 1500V DC, which is essential for working on hybrid and electric vehicles.
What is the torque range and adjustment increment?
The torque range is from 5 to 25 Newton-meters (Nm), with adjustments made in increments of 0.5Nm.
What does VDE certified mean?
VDE certification indicates that the product has been tested and meets the rigorous safety standards set by the VDE (Verband der Elektrotechnik Elektronik Informationstechnik) for electrical tools, particularly concerning insulation and safe live working.
How do I ensure the accuracy of the torque setting?
Ensure the adjustment collar is fully engaged after setting the torque. For best accuracy, always apply smooth, steady force. The wrench is calibrated to ±4% tolerance and supplied with a certificate of conformance. Periodic recalibration is recommended.
Can this wrench be used for general automotive repairs?
Yes, it can be used for any automotive repair that requires a torque setting between 5 and 25Nm. However, its specialized insulation is particularly beneficial for EV and hybrid applications.
What is the drive size of this torque wrench?
The drive size is 3/8 inches.
How should I store the torque wrench?
It should be stored in its supplied blow mold case. For long-term storage, it is recommended to set the torque wrench to its lowest setting (5Nm) to maintain the spring's condition.
What is the length of the wrench?
The wrench is 310mm in length.
Troubleshooting
Wrench does not 'click' at the set torque.
Ensure the torque is set correctly and the collar is pushed back in to lock the setting. Verify that you are applying smooth, continuous force. Check if the torque setting is at the very lowest end of its range, where the click may be less pronounced. If the issue persists, the wrench may require recalibration.
Difficulty adjusting the torque setting.
Ensure the adjustment collar at the base of the handle is fully pulled out before rotating. If it feels stiff, try gently wiggling it while rotating. Ensure no debris is obstructing the mechanism. If it remains stiff, contact customer support.
Scale reading appears inaccurate or worn.
Clean the scale gently with a dry cloth. If the markings are illegible or you suspect inaccuracy, the wrench should be sent for professional recalibration.
Insulation appears damaged.
Immediately cease using the wrench for live working and inspect the insulated handle and body thoroughly. If any cracks, nicks, or damage to the insulation are found, do not use the tool on live circuits and contact the manufacturer or a qualified repair service.
Pros and Cons
Pros
- Provides essential safety for live high-voltage work on EVs and hybrids.
- Precise torque application within its specified range.
- Clear and easy-to-use adjustment mechanism.
- VDE certification ensures high safety standards.
- Includes a calibration certificate for traceability.
Cons
- Limited torque range (5-25Nm) not suitable for all automotive tasks.
- May require a different torque wrench for applications outside this range.
- Insulation rating is specific to voltage and not environmental factors.
Setup, Compatibility & Care
Setup:
- Select Socket: Attach the appropriate 3/8" drive socket to the wrench.
- Set Torque: Pull out the collar at the base of the handle. Rotate the handle to set the desired torque value, reading the scale clearly. The adjustment is in 0.5Nm increments. Push the collar back in to lock the setting.
- Apply Torque: Apply smooth, steady force until the wrench 'clicks' audibly and tactilely, indicating the set torque has been reached. Avoid jerky movements.
Compatibility:
- This wrench uses standard 3/8" drive sockets. Ensure your sockets are in good condition.
- It is specifically designed for use on hybrid and electric vehicles due to its insulation properties, but can be used on any application requiring torque within its 5-25Nm range.
Care:
- Cleaning: Wipe clean with a slightly damp cloth. Do not use solvents or abrasive cleaners, especially on the insulated handle.
- Storage: Store the wrench in its supplied blow mold case when not in use to protect it from dust, moisture, and impact. It is recommended to set the torque wrench to its lowest setting (5Nm) for long-term storage.
- Calibration: While supplied with a calibration certificate, it's advisable to have it recalibrated periodically according to ISO6789 standards or after any significant impact or suspected inaccuracy to maintain its ±4% tolerance.
