Heat Resistance

These screws are highly heat-resistant among metal and plastic screws.
They can be used in high-temperature environments where there is a high risk of reduced screw strength or breakage.

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.
