Low Outgas

These are screws made of materials and surface treatments that emit low levels of outgassing.
Due to their minimal outgassing, these screws are ideal for vacuum environments such as vacuum chambers used in semiconductor manufacturing.
There are also titanium screws with low outgassing that have undergone brightening treatment.

Galling and Seizing

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.
