The “20 Rule” for Torque Wrenches

The “20 Rule” is a fundamental guideline for maximizing the accuracy and longevity of torque wrenches. It recommends operating these precision tools within a specific range of their maximum rated capacity, typically between 20% and 100% of their full-scale torque value.

Here’s why the “20 Rule” is crucial⁚

• Accuracy⁚ Torque wrenches are most accurate when used within their optimal working range. Operating below 20% of their capacity can lead to reduced sensitivity and less precise torque application, potentially affecting the reliability of your work.
• Wear and Tear⁚ Exceeding the maximum rated capacity of a torque wrench can subject its internal mechanisms to excessive stress, leading to premature wear and tear, potentially compromising its accuracy and reliability over time.
• Safety⁚ Over-tightening fasteners can lead to damage to components, potentially causing failure or even accidents. Adhering to the “20 Rule” ensures that you apply the correct torque, minimizing the risk of over-tightening and its associated safety concerns.

By following the “20 Rule,” you ensure that your Snap-on torque wrench delivers the optimal performance and accuracy while extending its lifespan and maximizing its overall value.

Calibrating Snap-on Torque Wrenches

Regular calibration is essential to ensure that Snap-on torque wrenches maintain their accuracy and reliability. This process verifies the wrench’s ability to deliver the correct torque value, ensuring consistent and precise tightening of fasteners.

Here’s a general overview of the calibration process⁚

• Specialized Equipment⁚ Calibration requires specialized equipment such as a torque tester or a hand-crank loader with a minimum accuracy of 0.5%; This equipment measures the applied torque with high precision.
• Authorized Centers⁚ Snap-on recommends that calibration be performed by authorized Snap-on Repair Centers or certified calibration laboratories. These facilities have the expertise and certified equipment to ensure accurate and reliable calibration.
• Calibration Procedures⁚ The calibration process typically involves loading the wrench to its full-scale torque value, verifying the accuracy of the reading, and adjusting the wrench if necessary. This process is repeated at various torque settings to ensure consistency across the wrench’s range.
• Calibration Certificate⁚ After successful calibration, a Calibration Compliance Certificate is issued, documenting the wrench’s accuracy and the date of calibration. This certificate serves as proof of the wrench’s compliance with industry standards and ensures its reliability for continued use.
