Bolted joints are a staple of modern engineering and manufacturing practice.
Modern life is modern because of our mastery of materials and bolted joints.
I would be hard pressed to name a technology that does NOT depend on bolted joints in some aspect of its construction and operation.
Here are two videos that describe the challenges faced by bolted joints.


When you see that piece of heavy equipment, man lift, or structural application, you can be assured that the engineers have evaluated the risk.
For those of us in manufacturing, these are great tutorials to stoke our “Mastery of our craft.”
In maching, bolting that secures our tools and fixtures is subject to the same challenges as shown in these films.
Enjoy.
Hat Tip to Jeff Remaley of Motch and Eichele for the find.
