Electrical Insulation

These screws have excellent electrical insulation properties.
They prevent current from flowing to electrical and electronic components, thereby preventing short circuits and damage to circuits.

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.
