Application
Vacuum devices, vacuum chambers, FPD production equipment,
semiconductor devices, and electron microscopes
Characteristics
- The ventilation hole easily releases gas trapped in the screw holes of equipment and machines, and supports vacuum drawing of vacuum devices.
- The flat head does not protrude after tightening.
Usage example
These screws are effective with vacuum devices and vacuum chambers that require the exhaustion of gas trapped in screw holes.
