Vacuum
They efficiently discharge gas accumulated in screw holes or drilled holes, achieving stability in vacuum levels and high vacuum.
The gas vent holes in NBK's vacuum equipment screws are processed in a way that minimally affects the metal structure, reducing the risk
of brittle fracture during use and the generation of outgassing in vacuum environments.
