Can I use a torque wrench to loosen bolts?

No, you should never use a torque wrench to loosen fasteners. Using it as a breaker bar can permanently damage the internal calibration mechanism. This is a leading cause of inaccurate readings and tool failure.

Always use a standard ratchet or breaker bar for loosening. Your torque wrench is a precision measuring instrument for tightening only. Protect your investment by following this fundamental rule.

What is the difference between foot-pounds and inch-pounds on a torque wrench?

Foot-pounds (ft-lbs) and inch-pounds (in-lbs) are different units of measurement for rotational force. One foot-pound equals twelve inch-pounds. Using the wrong unit will result in a massive torque error.

Use ft-lbs for high-torque applications like lug nuts. Use in-lbs for delicate tasks like interior trim or small engine components. Always double-check your vehicle manual to confirm the correct unit.

Why does my click-type torque wrench not click anymore?

A missing click usually indicates a damaged or worn internal mechanism. This can happen from over-torquing, using it to loosen bolts, or a significant drop. The spring or pawl assembly may be faulty.

Immediately stop using the wrench. It is no longer accurate and must be repaired or replaced. Contact the manufacturer if under warranty, or send it to a professional calibration shop for assessment.

What is the best way to store a click-type torque wrench long-term?

Always store a click-type wrench at its absolute lowest torque setting. This relieves tension on the critical internal spring, preventing loss of calibration. Never store it set to a high value.

Keep it in its original protective case in a clean, dry environment. Avoid temperature extremes. Following these storage steps is the simplest way to extend the tool’s accurate lifespan.

Are digital torque wrenches more accurate than mechanical ones?

High-quality digital torque wrenches can offer excellent accuracy, often ±1-2%. They provide visual and audible alerts, which some users prefer. However, they require batteries and can be more sensitive to environmental factors.

A well-calibrated mechanical click wrench (±3-4% accuracy) is perfectly sufficient for virtually all automotive work. The choice often comes down to personal preference and budget, not a significant accuracy gap for DIY use.

Do I need a different torque wrench for my car’s lug nuts and spark plugs?

Yes, these tasks require very different torque ranges and drive sizes. Lug nuts need a 1/2-inch drive wrench (typically 80-150 ft-lbs). Spark plugs need a 3/8-inch or 1/4-inch drive wrench (typically 15-30 ft-lbs).

Using one wrench for both is impractical. For a complete kit, consider owning two wrenches: a 1/2-inch for wheels/suspension and a 3/8-inch for engine work. This covers 95% of automotive applications.
