Using the correct drive size improves control and safety.
3. Check Measurement Units
Torque wrenches may show readings in Nm, ft-lb, in-lb, or kgf-m depending on the model.
For automotive work in the Philippines, Nm is commonly used in many service specifications. Choose a torque wrench with a scale you can easily read and convert if needed.
4. Consider Accuracy
For safety-related automotive work, accuracy matters. Choose a torque wrench with clear markings, solid build quality, and reliable adjustment.
Professional users may need calibration services depending on usage frequency.
5. Check Grip and Locking Mechanism
A comfortable handle and secure locking mechanism help prevent accidental setting changes during use.
This is especially useful for repeated tightening work.
How to Use a Torque Wrench Properly
Follow these basic steps:
- Check the required torque specification.
- Choose the correct socket size.
- Set the torque wrench to the required value.
- Make sure the socket is fully seated on the fastener.
- Pull the wrench smoothly and steadily.
- Stop when the wrench clicks or indicates the target torque.
- Do not continue tightening after the signal.
- After use, reset a click-type torque wrench to its lowest setting, if recommended by the manufacturer.
- Store the tool properly.
Always follow the torque wrench manual and the vehicle service information.
Important Torque Wrench Safety Tips
- Do not use a torque wrench as a breaker bar.
- Do not use it to loosen very tight bolts.
- Do not exceed the maximum torque rating.
- Use the correct socket size.
- Pull smoothly instead of jerking the handle.
- Keep the wrench aligned with the fastener.
- Stop once the target torque is reached.
- Do not drop the torque wrench.
- Store it in its case when not in use.
- Have it checked or calibrated when needed.
A torque wrench is a measuring tool, so it should be handled carefully.
Common Torque Wrench Mistakes to Avoid
Avoid these common mistakes:
- Guessing torque instead of checking specifications
- Continuing to pull after the wrench clicks
- Using the wrong torque range
- Using a torque wrench as a breaker bar
- Dropping or mishandling the tool
- Using damaged sockets
- Not resetting the wrench after use
- Tightening dirty or damaged threads
- Ignoring tightening sequence
- Using impact tools for final tightening without torque checking
Proper technique helps protect both the tool and the vehicle.
Torque Wrench vs Impact Wrench
A torque wrench and an impact wrench are not the same.
Impact Wrench
An impact wrench is used to loosen or quickly tighten nuts and bolts.
Best For
- Removing lug nuts
- Fast workshop work
- Heavy fastening
- Tire service
Torque Wrench
A torque wrench is used for accurate final tightening.
Best For
- Proper bolt tightening
- Wheel lug nut final torque
- Brake and suspension work
- Safety-related fasteners
In many automotive jobs, an impact wrench may be used for removal or initial fastening, but a torque wrench should be used for final tightening when torque accuracy is required.
Useful Tools to Pair With a Torque Wrench
A torque wrench works best with the right supporting tools:
- Socket wrench set
- Impact socket set
- Breaker bar
- Lug wrench
- Jack and jack stands
- Wheel chocks
- Work gloves
- Safety goggles
- Work light
- Vehicle manual or service guide
- Tool storage case
- Penetrating oil
- Thread cleaner, when needed
These tools help make automotive repair safer and more organized.
Basic Torque Wrench Maintenance Tips
1. Clean After Use
Wipe grease, dirt, and dust from the tool after use.
2. Store Properly
Keep the torque wrench in its case or a protected toolbox.
3. Avoid Dropping
Dropping the tool can affect accuracy.
4. Reset After Use
For click-type torque wrenches, follow the manufacturer’s instruction on resetting the torque setting after use.
5. Calibrate When Needed
Professional users should check calibration regularly, especially if the tool is used often or has been dropped.
