Frequently Asked Questions
How often should I calibrate my torque wrench?
Manufacturers typically recommend calibration every 5000 uses or once a year, whichever comes first. However, if you drop the wrench or use it as a breaker bar, you should have it recalibrated immediately to ensure accuracy.
What is the difference between click and digital torque wrenches?
Click wrenches use a mechanical clutch that makes an audible sound when the set torque is reached, requiring no batteries. Digital wrenches use a strain gauge and electronic display to show torque values in real time, often offering features like data logging and multiple unit measurements.
Do I really need a torque wrench for changing tires?
Yes, using a torque wrench is highly recommended for lug nuts to ensure they are tightened evenly and to the correct specification. Over tightening can warp brake rotors or damage studs, while under tightening can cause the wheel to come loose.
Can I use a torque wrench to loosen bolts?
No, you should never use a torque wrench to loosen frozen or tight bolts. The high impact force required to break a bolt loose can damage the internal calibration mechanism of the wrench. Always use a breaker bar for loosening.
What drive size should I choose for automotive work?
A 1/2 inch drive wrench is the most versatile for general automotive work, covering most lug nuts and suspension components. A 3/8 inch drive is better for smaller engine components and tight spaces, while a 1/4 inch drive is used for precision work on small fasteners.
