FASTENERS | Why Torque Can Lie

When you tighten a bolt, you’re not measuring how tight the joint is, you’re measuring resistance. And that resistance can change for a lot of reasons. In this video, we break down why torque doesn’t always equal clamp load, and how a fastener can feel tight… without actually holding anything together. From friction in the threads to what’s happening under the bolt head, small changes can lead to completely different results, even when the torque number is the same. We also walk through real failure examples, including bottoming out in a blind hole and bolts that stop at the shoulder before any clamp is created. If you want to understand how fasteners actually behave, and how to avoid being misled by torque, this is where it starts. ▶ Full Fasteners and Threads Playlist:    • FASTENERS | All About Fasteners and Thread...
