High Strength

These screws have high strength. They include screws made of particularly strong titanium, stainless steel, and plastic.
Using high-strength screws allows for smaller screw sizes while maintaining fastening force, contributing to more compact and lightweight equipment.

Galling and Seizing

This is a phenomenon that occurs while tightening, where the surface of the screw thread melts or welds due to frictional heat and the screw stops moving. To resolve galling, NBK's special surface treatment screws, such as those with fluorine coating, are recommended.

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.
