What is Torque Calibration?
Torque Calibration is the process of verifying and adjusting the accuracy of torque tools—such as torque wrenches, screwdrivers, testers, and sensors—to ensure they apply the correct amount of rotational force.
Why is Torque Calibration Important?
Torque Calibration is critical for product safety, mechanical reliability, and compliance with industry standards. Improper torque can lead to equipment failure, safety hazards, or warranty issues, especially in regulated sectors.
- Ensures accuracy of torque tools and equipment
- Meets quality standards (e.g., ISO 6789, ISO/IEC 17025)
- Improves product safety and reliability
- Reduces risk of over-tightening or under-tightening
- Supports traceable, consistent production and assembly processes
What Equipment Needs Torque Calibration?
Torque Calibration is needed across a wide variety of instruments, such as:
- Manual and Digital Torque Wrenches
- Torque Screwdrivers
- Torque Transducers and Sensors
- Hydraulic and Pneumatic Torque Tools
- Torque Testers and Analysers
Who Needs Torque Calibration?
Torque calibration is essential for any industry that uses torque tools to tighten bolts, fasteners, or rotating components. This includes:
- Automotive and motorsport industries (engine assembly, wheel fitting)
- Aerospace and defence (critical safety fastenings)
- Manufacturing and engineering (assembly line torque tools)
- Construction and infrastructure projects (steelwork and mechanical installations)
- Energy and utilities (wind, oil, gas, and nuclear industries)
- Medical device manufacturing (precision torque for implants and equipment)
- Calibration and test laboratories (traceable torque verification)
If your work involves torque wrenches, torque screwdrivers, pneumatic or hydraulic torque tools, or torque sensors, regular calibration is vital to ensure safety, compliance, and quality assurance.
How Often Should It Be Calibrated?
Torque calibration frequency depends on tool usage, regulatory standards, and application risk level:
- Every 6 to 12 months (standard for most industrial and trade applications)
- More frequently for high-precision or critical applications (e.g. aerospace, medical)
- After tool drops, damage, or suspected faults
- Before key projects or audits
- As required by ISO 6789, ISO 17025, or internal quality systems
Regular calibration helps prevent over-torquing or under-torquing—both of which can lead to serious safety issues or mechanical failures.
