Vol. 8 Why a Cross recess gets broken: What is "cam-out"?
Have you experienced "stripping" of a screw, where its cross recess reams out and prevents you from removing the screw? No one enjoys struggling to remove screws with pliers, right? Today, I will explain what "cam-out" is and how it causes cross recess to "strip."

The phenomenon in which a bolt that has been fastened for some time suddenly breaks is called delayed fracture. This can cause a lot of hassle, as the exterior shows no deformation and yet the bolts suddenly break. Why does delayed fracture occur? Under what conditions does it occur? How can we prevent it? Nedzigon makes it all clear to you.
Stress corrosion cracking Common Issues
Vol. 10 Stress Corrosion Cracking: corrosion that attacks corrosion-resistant stainless steel!
This is a description of "stress corrosion cracking", a problem that frequently occurs but is difficult to detect. I, Nedzigon will discuss the causes, mechanism, and countermeasures, as well as screws that are resistant to stress corrosion cracking.
Common Issues Galvanic Corrosion
Vol.13 Explaining the Rust Source "Galvanic Corrosion"
Have you ever been surprised by rust suddenly appearing on rust-resistant aluminum? If this happens, the reduced strength resulting from the corrosion brings fears of possible damage. This phenomenon is known as "galvanic corrosion". Today, I will explain this principle and how it can be handled.
