Torque testing & calibration

Every torque wrench, tested.

Torque wrenches are HOYOTOOL's flagship program. Each wrench is calibrated, tested to ±3% accuracy, and built to DIN torque standards before it leaves our factory.

±3%

Accuracy target

Every click torque wrench is tested and set to the real torque accuracy requirement before packing.

100%

Calibration

Each torque wrench is calibrated on controlled torque testing equipment, not treated as a sample-only check.

DIN

DIN standard

Built to DIN torque standards for buyers who need professional, verifiable torque tool programs.

HOYOTOOL torque testing and calibration lab

Factory QC lab

Calibration, torque verification, and recorded quality checks sit at the center of the torque wrench program.

Testing

Tested, not assumed

Torque wrench programs are checked through calibration, torque accuracy verification, dimensional control, and final inspection before they ship.
