Power And Torque Ratings
Choosing the best impact wrench for cars means understanding power and torque ratings. These ratings show how strong the tool is and what jobs it can handle.
Power and torque affect how quickly and easily you can remove or tighten bolts on your car. Knowing these numbers helps you pick the right wrench.
Why Torque Matters
Torque is the twisting force the wrench applies to bolts. High torque helps loosen tight or rusted bolts. Low torque may not work well on tough jobs.
- Proper torque ensures bolts are secure but not damaged.
- Too little torque can cause loose bolts, risking safety.
- Too much torque can strip threads or break bolts.
- Impact wrenches deliver torque quickly and efficiently.
- Check torque ratings before buying to match your needs.
Comparing Power Outputs
Power output shows how much energy the wrench uses. It affects speed and how long the tool can run without stopping.
| Power Type | Typical Power Range | Use Case |
|---|---|---|
| Electric (Corded) | 400 to 800 watts | Continuous work, no battery worries |
| Battery (Cordless) | 18 to 20 volts | Portable, good for most car repairs |
| Air (Pneumatic) | 90 to 120 PSI | High power, best for heavy-duty jobs |
