In industries where bolts, nuts, and fasteners play a critical role, applying the correct torque is essential. Too little torque can lead to loose connections, while excessive torque can damage components. This is where torque calibration services become crucial. By ensuring that torque tools deliver accurate and consistent force, these services help maintain quality, safety, and reliability across various industries.
From automotive manufacturing to aerospace and heavy engineering, torque calibration is a fundamental part of quality assurance.
What is Torque Calibration?
Torque calibration is the process of verifying and adjusting torque tools—such as torque wrenches, screwdrivers, and multipliers—to ensure they apply the correct amount of force. Over time, regular use and environmental factors can cause these tools to drift from their original settings.
Calibration is typically performed according to standards like ISO/IEC 17025, ensuring accuracy and traceability.
