TEKTON TRQ52402 1/2 Inch Drive Micrometer Torque Wrench vs GEARWRENCH 85176CERT 3/8 Inch Drive 120XP Certified Micrometer Torque Wrench
Which should you buy? Our verdict on both, pulled from our full The Best Torque Wrenches: 4 Compared (and One to Skip) comparison.
The TEKTON is the one to buy first: half inch drive for the wheel and suspension work most people bought a torque wrench for, which TEKTON rates to the stricter ISO standard in both directions, with a serialized certificate. The GEARWRENCH is the three eighths drive companion that reaches down to 10 ft-lb for engine and brake fasteners, with a NIST traceable certificate of its own.

Buy itRated by TEKTON to the stricter ISO standard in both directions, with a serialized certificate in the case.
- Rated within plus or minus 3 percent clockwise and counterclockwise, not clockwise only
- Calibrated to ISO 6789-1:2017, which tests the lowest marked value on the scale
- Serialized certificate of calibration in the box, listing the actual readings for your wrench
- Range starts at 40 ft-lb, so nothing lighter than suspension and wheel work is on the scale
- You still need a three eighths drive wrench for engine bay fasteners
