Material/Finish
| SVSS-SD | |
|---|---|
| Main Body | SUSXM7 (Equivalent to SUS304) |
| Strength Class | A2 - 70 |
Application
Vacuum devices / Vacuum chambers / FPD production equipment / Semiconductor manufacturing equipment / Electron microscopesCharacteristics
- Small head screws with ventilation holes. Because the head diameter is small, spot facing diameters can be reduced compared to standard hex socket head cap screws.
- The ventilation hole easily releases gas trapped in the screw holes of equipment and machines, and supports vacuum drawing of vacuum devices.
- Ventilation holes are machined using a method with minimal effect on metallic structures. Brittle fracture and outgassing during use in vacuum environments are prevented.
- Cleanroom wash/cleanroom packing provided.⇒Cleanroom Wash / Cleanroom Packing Service
Usage Example
Gas trapped at the bottom of the screw hole is released through SVSS-SD, and gas trapped in the drilled hole is released through SWAS-VF.SWAS-VF
Precautions for Use
- Since the head bearing surface area is small, the bearing surface pressure increases.
- Using the following formula as a reference, ensure that the bearing surface pressure due to screw tightening does not exceed the permitted surface pressure of the intended fastening material.
