Torque Wrench Calibration
Instrument Calibration Solutions (ICS) calibrates torque wrenches from 4 lbf·in to 600 lbf·ft under A2LA ISO/IEC 17025 accreditation, in our Aliquippa, PA and Clayton, OH labs or on-site at your facility. We also calibrate the torque analyzers and transducers used to check wrenches, up to 2,200 lbf·ft.
Accredited Torque Capability
| Equipment | Range | Best uncertainty (CMC) | On-site |
|---|---|---|---|
| Torque wrenches and torque measuring equipment | 4 lbf·in to 600 lbf·ft | 0.25 % to 0.6 % depending on range | Yes, both labs |
| Torque analyzers and transducers | 2.5 lbf·in to 2,200 lbf·ft (Aliquippa); to 250 lbf·ft (Clayton) | From 0.02 % + 0.012 lbf·in | Lab |
Both labs use Snap-On TTC400 torque calibration systems for wrenches and calibrated arms and wheels with ASTM Class 6 weights for analyzers. See our scopes of accreditation (Aliquippa 2332.01, Clayton 2332.02).
What We Calibrate
- Click-type, dial, beam and electronic torque wrenches
- Torque screwdrivers within range
- Torque analyzers, testers and transducers
What You Get
Each wrench is cleaned and inspected, tested across its range with as-found readings recorded, adjusted if it is out of tolerance, and retested for as-left data. Certificates are posted to ICS LIVE with your next due date.

Frequently Asked Questions
What torque wrench range does ICS calibrate?
Torque wrenches and torque measuring equipment from 4 lbf·in to 600 lbf·ft at both labs. Torque analyzers and transducers are calibrated from 2.5 lbf·in up to 2,200 lbf·ft at our Aliquippa, PA lab and up to 250 lbf·ft at Clayton, OH.
Can torque wrenches be calibrated on-site?
Yes. Torque measuring equipment is listed for field calibration on both ICS scopes, so we can calibrate wrenches at your facility.
How often should torque wrenches be calibrated?
A 12-month or 5,000-cycle interval, whichever comes first, is common. Calibrate sooner if a wrench is dropped, overloaded or used as a breaker bar.
Is torque calibration accredited?
Yes. Torque calibration is on the A2LA ISO/IEC 17025 scopes of both ICS labs (Certificates 2332.01 and 2332.02).
