How often should you calibrate your torque tools?

The ISO standard for calibration intervals is every 5,000 cycles or once a year.

Torque tool calibration ensures the accuracy and consistency of the applied torque, preventing potential damage to equipment, safety hazards, and product failures by guaranteeing that fasteners are tightened to the correct specifications, ultimately maintaining quality and compliance with industry standards

Essential Safety Tips for Using Torque Tools

Here are some essential safety tips for working with torque tools, covering everything from maintenance and storage to practical everyday use:

Read the Manual

Even the best tools are only safe when used correctly, and a torque wrench is no exception. To maximize the lifespan of your torque tools and minimize injury risk, it's crucial to understand how they work. Take the time to read the manual thoroughly.

Wear the Right Safety Gear

Torque jobs might seem low-risk, but the forces involved are significant, and materials can be under immense strain. Torque wrenches can slip, and bolts can crack or split, potentially sending debris flying. Always wear safety glasses and gloves to protect yourself.

Inspect the Wrench and Fittings

Before starting any torque job, carefully inspect the torque tool and the fastenings. Look for any cracked or worn sockets on the wrench and any signs of damage on the bolts. If you notice any issues, pause the job and have your tool inspected, repaired, and recalibrated.

Always Pull, Never Push

The force involved in torque jobs can be substantial, and it might be tempting to use your body weight. However, pushing on a torque wrench can lead to slips and falls. Always pull the wrench, maintain a steady stance with your feet apart, and be ready to adjust your balance if the tool slips.

Stick to the Limits

Manufacturers set specific ranges for their tools for a reason. Exceeding these limits can be dangerous. Mechanical torque wrenches are typically calibrated from 20% to 100% of full scale. Aim to use the tool at around 50% of its capacity, and have multiple torque tools with different calibrations for various fastenings.

Check After Any Impact

A calibrated torque tool is delicate and can be affected by minor damage or environmental changes. If you drop your tool or it takes an impact, stop the job and get the tool checked and recalibrated.

Store It with Care

Proper storage is crucial for maintaining the accuracy and integrity of your torque tools. Store them in protective cases, away from heat sources, corrosive substances, and excessive moisture. For click-type wrenches, always store them at the lowest setting on the scale.

By following these tips, you can ensure the safety of your team and the longevity of your tools. Stay safe and work smart!
