Are You Using the Correct RAD Torque Gun Settings?
Ensuring proper torque application during critical bolting procedures is essential for maintaining equipment integrity and worker safety. However, using the incorrect torque gun settings can lead to a cascade of issues, ranging from loose and leaky connections to stripped threads and even catastrophic equipment failure.
As experienced industrial suppliers, we frequently see issues stemming from improper tool use. We take a closer look at the importance of using the correct RAD Torque Gun settings and provide valuable insights to help you achieve optimal results in your bolting applications.
Understanding Torque Values and Settings
Torque refers to the twisting force applied to a fastener and is measured in foot-pounds (ft-lbs) or newton-meters (Nm). Every bolt, nut, and screw has a specific required torque value designated by the manufacturer. Using an impact wrench or torque wrench set to the incorrect torque gun setting can have serious consequences:
- Over-tightening – Applying excessive torque can damage threads, warp components, and even lead to fastener breakage. This can compromise joint integrity and increase the risk of leaks or equipment failure.
- Under-tightening – Insufficient torque leaves the joint loose, potentially leading to leaks, vibration, and, ultimately, fastener loosening. This can pose significant safety hazards and necessitate costly repairs.
Finding the Right Torque Gun Setting
You can typically find the designated torque value for a specific fastener in the manufacturer’s assembly manual, service instructions, or data sheets. It’s crucial to consult these resources before commencing any bolting operation.
Configuring a Manual Torque Wrench or Gun
Manual torque wrenches, like RAD’s B-RAD torque wrench, often have quick reference torque chart labels on the tool’s barrel. Operators can check the chart and then rotate the quick grip torque to the necessary torque setting.
Once ready, operators need to select forwards or reverse (depending on whether they’re tightening or loosening). Once the operator depresses the trigger, the torque gun is ready to go.
Configuring a Digital Torque Wrench or Gun
RAD’s digital torque wrenches or guns take the guesswork out of setting adjustments. The wrench’s body contains a digital strain gauge that displays applied torque in real time on an LED screen. This torque value updates continuously as you tighten.
To set the desired torque, digital models have intuitive plus/minus buttons to dial in the target value based on units like ft-lbs or Nms. Some RAD models, like the E-RAD BLU, have color-coded displays, showing green when you’ve reached your target torque setting, red when you’ve failed, and blue when the tool is ready to use.
In all cases, proper calibration is essential to maintain the accuracy of your torque wrench setting over time.
Using Your Torque Gun Effectively
Once you’ve identified the correct torque setting, it’s vital to use your torque gun properly:
- Double-check the setting – Verify that the torque wrench is set to the exact value specified for the fastener.
- Use the right tool for the job – Impact wrenches are ideal for initial tightening, while torque wrenches provide the precision needed to achieve the final desired torque.
- Follow a proper tightening sequence – Tighten fasteners in a specific order, often in a star pattern, to ensure even load distribution.
- Use a calibrated torque gun – Regularly calibrate your torque gun according to manufacturer recommendations to maintain accuracy.
