Hex socket Head Cap Screws with Ventilation Hole / Surface Hardening Treatment 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. Application Seizing Prevention Vacuum devices / Vacuum chambers / FPD production equipment / Semiconductor devices / Electron microscopes / Food industry machines Material: SUS316L Surface hardening treatment Strength Class A4-70
