What to look for
Questions worth asking
What is the difference between a click and a beam torque wrench?
A click torque wrench makes a clicking sound when the desired torque is reached, indicating you should stop. A beam torque wrench has a needle that shows the torque as you tighten, requiring you to watch the gauge. Click wrenches are more common and easier to use in tight spaces.
How often should I calibrate my torque wrench?
It depends on usage. If you use it daily, calibrate every 6 to 12 months. If you use it occasionally, every 2 to 3 years is sufficient. Many manufacturers offer calibration services. Some wrenches come with a certificate of calibration.
Can I use a torque wrench for loosening bolts?
No, you should never use a torque wrench to loosen fasteners. It can cause the internal mechanism to lose accuracy. Use a regular breaker bar or ratchet to loosen bolts, then use the torque wrench only for tightening.
What is the proper way to store a torque wrench?
Always set the torque wrench to its lowest setting before storing. This relieves tension on the internal spring, maintaining accuracy. Store it in a dry place, preferably in its original case.
What does +/- 4% accuracy mean?
It means the wrench can be off by up to 4% of the set torque value. For example, if you set it to 100 ft-lb, the actual torque applied could be between 96 and 104 ft-lb. Higher quality wrenches have lower percentages.
Do I need a 1/2-inch or 3/8-inch drive torque wrench?
It depends on the torque range you need. 1/2-inch drive wrenches typically handle higher torque (up to 300 ft-lb) and are used for larger fasteners like lug nuts. 3/8-inch drive wrenches are for lower torque applications (up to 100 ft-lb) and are good for engine work.
Are digital torque wrenches more accurate than click types?
Generally, digital torque wrenches have a higher accuracy rating, often +/- 2% or better. They are also easier to read. However, they require batteries and may be more expensive. Click wrenches are reliable and don’t need power.
Can I use a torque wrench for bicycle repairs?
Yes, but bicycle fasteners often require lower torque values, typically between 4 and 20 Nm. You would need a torque wrench with a low range, such as a 1/4-inch drive model. Using a high-range wrench for low torque is not recommended.
What is the best torque wrench for lug nuts?
For lug nuts, a 1/2-inch drive torque wrench with a range of 50-150 ft-lb is ideal. The TEKTON 24325 or the CDI 2503MFRPH are both excellent choices. Make sure to check your vehicle’s recommended torque specification.
Why does my torque wrench click before reaching the set torque?
This can happen if the wrench is not calibrated or if it was dropped. It may also occur if you are using the wrench at the very low end of its range. If it happens consistently, have the wrench recalibrated or replaced.
Our take
For the majority of mechanics, the TEKTON 24325 is the best all-around torque wrench. It provides reliable accuracy, a comfortable feel, and a price that fits most budgets. If you demand the highest precision for professional work and are willing to spend more, the CDI 2503MFRPH is the top choice. For those who prefer a digital readout, the Lexivon LX-181 offers excellent features at a reasonable cost. Whichever you choose, any of these torque wrenches will help you work with confidence.
