Socket Head Cap Screw (with Ventilation Hole)

SVSL

SUS316L has excellent corrosion-resistance.
May be used with vacuum chamber applications in clean rooms, FPD (Flat Panel Display) production equipment and semiconductor devices.
All clean washed. Clean wash format minimizes gas diffusion and prevents foreign particle inclusion.
The SVSL-PC PC Chemical Polish improves surface roughness and reduces diffusion to microscopic levels.
Material/Finish: SUS316L
SVSL : Without Surface Treatment
SVSL-PC : Special Chemical Polish
Applications
Remove trapped gases in the pilot bore through the ventilation hole.
May be used with vacuum equipment and vacuum chamber applications.
We manufacture specialty-use product dimensions, profiles, materials, surface treatments, and special packaging.
