Material/Finish

SVSL-PN
Main Body SUS316L
Surface hardening treatment
Strength Class A4-70

Application

Seizing Prevention
Vacuum devices / Vacuum chambers / FPD production equipment /
Semiconductor devices / Electron microscopes / Food industry machines

Characteristics

  • The ventilation hole easily releases gas trapped in the screw holes of equipment and machines, and supports vacuum drawing of vacuum devices.
  • Hardening the screw surface prevents screw seizing / sticking.
  • Unlike platings or coatings, there is nothing adhering to the surface, eliminating concerns about contamination due to stripping during tightening.
  • Suitable for prevention of seizing in environments where lubrication cannot be used.
  • Cleanroom washed and packed. ⇒Cleanroom Wash / Cleanroom Packing Service

Usage Example

Gas trapped at the bottom of a screw hole is released through SVSL-PN, and gas trapped in a drilled hole is released through SWAS-VF
(SWAS-VFSWAS-VF-PC).

Precautions for Use

May have lower corrosion resistance than general SUS316L.
We recommend performing a test under the same usage conditions as in actual usage in advance.
