What Is a Torque Wrench?
A torque wrench is a precision fastening tool used to apply a specific amount of torque to a fastener. Torque wrenches help teams tighten bolts, screws, and fittings to required specifications so assemblies perform safely and consistently.
Torque wrenches are commonly used in manufacturing, aerospace, defense, medical device production, automotive, energy, maintenance, and quality control environments. Because incorrect torque can lead to under-tightening, over-tightening, leaks, part damage, or assembly failure, regular calibration helps confirm that torque tools remain accurate, traceable, and suitable for use.
Common Torque Tools
SIMCO supports calibration for common torque tools and related equipment, including:
- Click-style torque wrenches used for repeatable fastening in production and maintenance environments
- Digital and electronic torque wrenches used for advanced torque measurement, data capture, and traceable assembly workflows
- Beam-style torque wrenches used for rugged manual torque applications
- Dial-type torque wrenches used for applications requiring visible torque indication
- Torque drivers used for lower-torque fastening applications
- Torque transducers and sensors used in R&D, automated systems, and quality control environments
- Torque analyzers and testers used to verify torque tool performance
Torque Wrench Calibration Capabilities
SIMCO provides torque wrench calibration services designed to verify torque accuracy, identify drift, and support traceable documentation for quality and compliance programs.
Our torque wrench calibration services may include:
- Inspection for wear, damage, misuse, loose components, or mechanical issues
- As-received testing to document tool performance before adjustment
- Multi-point torque verification across the specified operating range
- Clockwise and counterclockwise verification, when applicable
- Calibration for click, dial, beam, digital, electronic, and torque driver tools
- Torque transducer, sensor, analyzer, and tester calibration, when applicable
- Adjustment, when supported by the tool and service scope
- As-found and as-left results, when required
- Calibration certificates with measurement results, tolerances, uncertainties, and traceable documentation
Why Torque Wrench Calibration Matters
Torque tools can drift over time due to repeated use, spring fatigue, overload, impact, improper storage, vibration, temperature changes, humidity, or normal wear. If a torque wrench applies too much or too little torque, fastening quality and assembly performance can be affected.
Calibration helps support:
- Torque accuracy: Confirms torque tools apply force within required tolerances.
- Assembly quality: Helps ensure fasteners are tightened consistently to required specifications.
- Compliance and audit readiness: Provides traceable documentation for quality systems, customer requirements, and regulated environments.
- Risk reduction: Helps reduce under-tightening, over-tightening, leaks, part damage, rework, warranty issues, and assembly failures.
