FAQs About Torque Testing
5. Your Burning Torque Questions Answered!
Hopefully, you now have a good understanding of what torque testing is and why it's so important. But you might still have a few questions. Let's address some of the most common ones to clear up any remaining confusion.
Q: What happens if you over-torque a bolt?A: Over-torquing a bolt can damage the threads, weaken the fastener, or even cause it to break. It can also deform the materials being clamped, leading to a loss of clamping force. Think of it like stripping a screw; you've essentially ruined the connection.
Q: What happens if you under-torque a bolt?A: Under-torquing a bolt can lead to loosening, reduced clamping force, and eventual failure of the joint. Vibration and stress can cause the bolt to gradually work its way loose, potentially leading to catastrophic consequences.
Q: Can I perform torque testing myself?A: Yes, you can, but it's important to use the correct tools and follow the manufacturer's instructions. A calibrated torque wrench is essential for accurate results. If you're working on critical applications, it's best to consult with a qualified technician.
Q: How often should I re-torque bolts?A: The frequency of re-torquing depends on the application and the materials being used. Some applications require periodic re-torquing, while others may not. Consult the manufacturer's specifications for guidance. A general rule of thumb is to check critical fasteners periodically, especially in high-vibration environments.
