Every bolt that matters has a torque spec. Lug nuts, head bolts, spark plugs, and suspension fasteners all require specific tightening force. A click-type torque wrench tells you when you've reached the target. The Tekton 24335 and GearWrench 85099 are both 1/2-inch drive, both cover 10 to 150 ft-lbs, and both cost around $40. The difference is in build quality and long-term accuracy.
Quick Verdict
The GearWrench 85099 is the better torque wrench by a small margin. The +/- 3% accuracy, louder click, and better grip make it more trustworthy in daily use. The Tekton 24335 is equally functional and $1 less. For $42 to $43, both are solid. The GearWrench edge shows up most when you're torquing critical fasteners where that extra 1% accuracy matters.
+/- 3% accuracy gives tighter tolerance on head bolts, rod bolts, and main caps where precision matters most.
Louder click is easier to feel and hear when kneeling next to a wheel in a parking lot.
Functionally identical for weekend work. $1 less with the same range and NIST-traceable calibration.

Tekton 24335
Price: $42 (Amazon)
Pros
- 1 ft-lb increments on the micrometer scale allow precise target setting
- 72-tooth ratchet head gives a 5-degree swing arc, useful in tight bolt patterns
- Includes a calibration certificate traceable to NIST standards
Cons
- +/- 4% accuracy is acceptable but not the tightest in this class
- Plastic handle grip can feel slippery with oily hands
- Click is quiet, easy to miss in a noisy shop without paying attention
GearWrench 85099
Price: $43 (Amazon)
Pros
- +/- 3% accuracy is the tightest spec in the sub-$50 torque wrench class
- Louder, more definitive click that's hard to miss even in a noisy environment
- Knurled aluminum handle provides better grip with oily or gloved hands
Cons
- Slightly shorter overall length reduces leverage on high-torque applications
- Ratchet head is marginally thicker, occasionally matters in recessed bolt holes
- Scale markings are smaller and harder to read in dim lighting

Frequently Asked Questions
How often should I recalibrate a torque wrench?
The general rule is every 12 months or every 5,000 cycles, whichever comes first. If you drop it or it gets hit hard, recalibrate immediately. Both Tekton and GearWrench offer factory recalibration service for around $20 to $25.
Should I store the torque wrench at the lowest setting?
Yes. Always back the micrometer scale down to the lowest setting before storing. Leaving the spring compressed at a high setting weakens it over time and shifts the calibration. Both manuals specify this.
Can I use a torque wrench to loosen bolts?
You can turn it counterclockwise to loosen, but the click mechanism only works in the clockwise direction on these models. Using it as a breaker bar risks bending the beam and ruining the calibration. Use a breaker bar or impact wrench for loosening.
