Quality
Quality you can verify
Every HOYOTOOL torque wrench is calibrated, tested to +/-3% accuracy, and checked against ISO 6789, ASME B107.14, DIN, CE, and TUV-GS program requirements before final inspection.
Torque testing & calibration
Every torque wrench, tested.
Torque wrenches are HOYOTOOL's flagship program. Each wrench is calibrated, tested to ±3% accuracy, and checked against ISO 6789, ASME B107.14, DIN, CE, and TUV-GS program requirements 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.
ISO+
Standards
Built for ISO 6789, ASME B107.14, DIN, CE, and TUV-GS aligned torque tool programs.
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.
Hardness
Rockwell hardness checked for the right balance of strength and toughness.
- Rockwell testing
- Stable HRC range
- Material traceability
Dimensional
Drives and profiles gauged to spec for fit and durability.
- Go / no-go gauging
- Drive tolerance
- Profile inspection
Salt-spray
Plated and finished surfaces tested for corrosion resistance.
- Salt-spray chamber
- Anti-corrosion finish
- Finish consistency
Traceability
Batch-level traceability
Quality is recorded, not assumed - every batch can be traced back through the line.
