Torque wrench and torque tool calibration
Torque work depends on the tool type, operating range, test points and direction. Verified ANAB AC-3279 coverage is for Hand Torque Tool (Torque Wrench) from 1 to 1,000 N·m; other torque instruments require separate service and accreditation review.

Review method, points, scope and conditions before quotation.
Calibrate
Follow the agreed work; adjust only with authorization.
Review results
Check the certificate and suitability against operating criteria before use.
Torque tool details needed for calibration
Send tool and nameplate photos so SK can review the type, range and method. Submitted instrument names do not mean all models are accredited.
- Torque wrenches: identify operating or indication type, brand, model and identifier.
- Provide range, units, drive size and accessories actually used.
- State working directions, critical torque points and criteria.
- Torque screwdrivers, testers and other tools need separate service and accreditation review.
Prepare torque wrenches before dispatch
Complete information and accessories help define work that represents use. Declare damage or abnormal operation before handover.
- Include case, specific accessories, manual and previous certificate if available.
- Declare impact, repair or adjustment history.
- Do not adjust before agreeing work if as-found results are needed.
- Protect against transport impact and follow manufacturer storage instructions.
Review and apply torque calibration results
A certificate does not automatically establish compliance for every job. Review results with process criteria and agreed conditions.
- Confirm identifier, unit, direction and reported points.
- Evaluate results, error and uncertainty with acceptance criteria.
- Agree criteria and decision rule before requesting pass/fail statements.
- Calibration, adjustment and repair are separate work; confirm scope and charges.
Frequently asked questions
Are all torque tools covered by ANAB accreditation?
No. Verified coverage specifies Hand Torque Tool (Torque Wrench). Confirm actual type, range and method before accreditation is confirmed.
What does torque wrench calibration cost and how long does it take?
It depends on type, range, direction, points, quantity, condition and adjustment needs. Send details and required date to confirm cost and delivery.
Can both clockwise and anticlockwise directions be calibrated?
Specify actual directions so the team can check tool capability and method. Results for one direction should not replace another without assessment.
Do torque screwdrivers and testers share the same scope?
Do not infer coverage of all torque tools from torque wrench accreditation. Send model, range and use for separate assessment.
How often should torque wrenches be calibrated?
Use frequency, risk, result history, condition and manufacturer or quality requirements determine the interval. Assess impact damage or abnormal operation before returning a tool to service.
Which torque points should be specified?
Provide frequently used and critical points, direction and criteria to plan suitable calibration points.
Is adjustment required at every calibration?
No. Calibration reports values under defined conditions; adjustment is separate and must be agreed. Request as-found and as-left results when needed for retrospective assessment.
