Torque Wrench Calibration Services
A torque wrench you can’t trust is worse than no torque wrench at all. Whether you’re torquing head bolts on a production line, closing out aircraft maintenance, or documenting fastener specs for an auditor — the number on the dial only matters if it’s true.
ACS Calibration delivers NIST-traceable, audit-ready torque wrench calibration, available at the ACS central lab or directly on-site at facilities across the Southeast. Torque wrenches are on our accredited scope, so ISO/IEC 17025 accredited certificates are available on request.
Torque Tools We Calibrate
If it clicks, reads, or measures torque, we can almost certainly handle it.
Frequently serviced brands: Snap-on, CDI Torque Products, Sturtevant Richmont, Tohnichi, Proto, Husky, Westward, Wiha, and GearWrench — plus dozens more.
Torque Tools Drift — Here’s What We Do About It
A click-type torque wrench is a spring under load. Every cycle relaxes that spring a little, and a single drop on concrete — or a season stored wound up at full scale — can push it out of tolerance with no visible sign. That’s why most quality systems calibrate torque wrenches at least annually, and put high-use production tools on a shorter interval based on cycle counts.
We calibrate every common style: click-type, dial, digital and electronic, beam-style, and preset wrenches, along with torque screwdrivers, torque meters and analyzers, and torque setting devices. Each tool is exercised and tested at multiple points across its working range in the direction of use, with as-found and as-left readings recorded — so you can see exactly how far it drifted since its last calibration, and stand behind the parts you torqued in between.
That documentation matters anywhere a fastener failure is expensive: production assembly lines, aircraft and fleet maintenance sign-offs, medical device manufacturing, structural bolting. If your program covers force measurement too, we calibrate force gauges, load cells, and dynamometers in the same shipment — and if the tools can’t leave your floor, onsite calibration brings the lab to you.
What You Get With Every Calibration
- NIST-traceable calibration certificate with real measurement data — not just a pass/fail sticker
- As-found and as-left readings, so drift is documented
- ISO/IEC 17025 accredited certificate with reported uncertainty — on request
- Calibration label with due date, plus a reminder before your next calibration is due
Why Companies Choose ACS for Torque Calibration
NIST-Traceable, Accredited on Request
Every calibration is NIST-traceable with real measurement data. Torque wrenches are on our ISO/IEC 17025 accredited scope — accredited certificates available whenever your quality system requires them.
4–6 Business Day Typical Turnaround
Keep production moving. Most torque tools are typically completed in 4 to 6 business days from arrival, with rush options available when a line is down.
Flexible Logistics
Mail your wrenches in, or schedule onsite calibration and we come to your floor — serving Alabama, Florida, Georgia, Mississippi, Tennessee, South Carolina, and beyond.
