Choose a calibrated range for the fastener.
TRQ50402 covers 20–200 in-lb for smaller specified fasteners. The 3/8-inch GEARWRENCH 85062M covers 10–100 ft-lb, while TRQ52403 extends to 40–300 ft-lb. Choose around service specifications, access and the drive tools you already own. The ranges overlap in places but use different units; buying the largest wrench will not cover every small fastener.
The TEKTON selections document dual-direction measurement. GEARWRENCH declares ±3% clockwise accuracy at 20–100% of full scale; do not extend that accuracy claim to every lower setting or reverse-direction use. Confirm the specified unit, direction and sequence. An impact-wrench setting does not establish final torque.

TRQ50402 1/4-inch torque wrench with case
A click-type torque wrench for tightening suitable fasteners to a specified torque. Match its drive size and working range to the service information for the jobs you expect to do.
Its 20–200 in-lb range does not cover lower 10–19 in-lb settings. Use a different calibrated range when a fastener requires it.
TRQ52403 1/2-inch torque wrench with case
A second torque-wrench option for a different working range and drive requirement. Choose it around actual fastener specifications and access, rather than buying two overlapping ranges automatically.
Its 40–300 ft-lb range does not cover lower 25–39 ft-lb settings. Final tightening follows the vehicle specification, not impact-wrench settings.
3/8-inch micrometer torque wrench
A mid-range torque wrench that fills part of the gap between a small inch-pound wrench and the larger 1/2-inch TEKTON. Its 3/8-inch drive is useful where socket size, access and service torque suit this range.
Check units and tightening direction. The published accuracy declaration covers clockwise use in the upper 80% of full scale; do not assume identical accuracy at every low setting.
