Nut vs. Bolt Failure: Which Should Fail First in Bolted Joint Design?

Should the nut or bolt fail first—and why does it matter?

In this episode of Tech Talks with Bossard, Application Engineering Manager Doug Jones breaks down a question every design engineer should consider: how to manage failure in a bolted joint.

💡 Here's what you'll learn:
- Why the bolt should always fail before the nut in joint design
- How torque, clamp load, and friction interact in real-world assemblies
- What happens when your clamp load exceeds your fastener strength
- How using a weaker bolt helps ensure safer, more predictable outcomes

This video is for engineers looking to reduce the risk of unseen failures, avoid expensive downtime, and optimize their joint design strategy from the start.
