If your team relies on torque tools, you already know calibration is critical. But how you maintain accuracy, when to verify performance, and which tools you use between calibrations can dramatically improve reliability on the floor.
This guide is built specifically for technicians, maintenance leads, and quality teams—the people responsible for keeping torque tools in spec every day.
What “Calibration” Actually Means in the Field
Calibration isn’t just paperwork. It means:
- Comparing your torque tool’s output against a certified reference
- Adjusting the tool (if necessary) to fall within acceptable tolerances
- Documenting results for compliance and traceability
Actionable Recalibration Intervals
Use these benchmarks to build your calibration schedule:
| Tool Type | Suggested Calibration Interval |
|---|---|
| Click Wrenches | Every 5,000 cycles or 6–12 months |
| Digital Torque Tools | Every 3–6 months or 10,000 cycles |
| Pneumatic Screwdrivers | Every 2–8 weeks (especially in high volume) |
| Electric Screwdrivers | Every 3–6 months, or every 2,500 cycles |
| Critical Tools (Aerospace) | Per ISO 17025: before each use, plus lab-cal quarterly |
⚠️ If a tool is dropped or misused—recalibrate immediately.
On-the-Floor Verification: The Overlooked Step
Formal calibration happens off-site or via a certified lab. But daily verification should happen on the line.
Technicians should check tools at the start of each shift with a reliable tester like the:
- ✅ Mountz EZ-TorQ III Analyzer: Compact, fast, and NIST-traceable
- ✅ Mountz Torque Sensors: For rotary and inline tool testing in production environments
- ✅ Exacta 2 1250 Series Digital Wrenches: With built-in verification mode and traceable audit logging
Daily checks won’t replace calibration—but they catch drift before it impacts your product.
What to Track & Document
Technicians should log:
- Torque output during verification
- Calibration due dates
- Tool serial numbers
- Results of any failed checks or issues found
Pair this data with traceability tools and you’ll be audit-ready with minimal effort.
Tips for Extending Calibration Life
- Store tools in protective cases or padded drawers
- Avoid using torque tools as break bars
- Ensure operators understand proper click or slip point usage
- Use preset tools where possible to avoid tampering

Final Word: Make Calibration Practical
When calibration is treated as a daily process—not a yearly chore—your team will spot problems sooner, reduce rework, and pass audits with ease.
