Torque Wrench Calibration: Why It Matters and How to Do It
Precision is everything in mechanical and industrial work. Whether you’re tightening bolts on a vehicle engine, assembling aircraft parts, or working on heavy machinery, the accuracy of your torque settings can make or break the job. That’s where torque wrench calibration comes in. While a torque wrench is designed to apply a precise amount of torque to a fastener, its accuracy can drift over time due to wear, misuse, or environmental conditions. Regular calibration ensures that your wrench is delivering the correct torque every single time, helping you maintain safety, performance, and compliance. Why Torque Wrench Calibration Matters Accuracy Assurance Even the most high-end torque wrenches can lose accuracy with regular use. Calibration confirms that your torque wrench is delivering torque within the specified tolerance range—usually ±3% to ±5% for most professional tools. Prevent Mechanical Failures If bolts are over-tightened, they may strip threads, crack components, or...
