| Main Body | SUSXM7 (Equivalent to SUS304) |
| Strength Class | A2 - 50 |
Application
Vacuum devices / Vacuum chambers / FPD production equipment / Semiconductor manufacturing equipment / Electron microscopesCharacteristics
- Special low profile small head screws with ventilation holes.
- The ventilation hole easily releases gas trapped in the screw holes of equipment and machines, and supports vacuum drawing of vacuum devices.
- All head heights are 1.5 mm or less. For space-saving of equipment/devices and applications with limited overhead space.
- Because the head diameter is small, spot facing diameters can be reduced compared to standard hex socket head cap screws with ultra low heads.
- Cleanroom wash/cleanroom packing provided.⇒Cleanroom Wash / Cleanroom Packing Service
Usage Example
Effective with vacuum devices and vacuum chambers that require the exhaustion of gas trapped in screw holes.
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.
