Hexagon Head Bolts (with Ventilation Hole) The ventilation hole easily releases gas trapped in the screw holes of equipment and machines, and supports vacuum drawing of vacuum devices. The ventilation hole is machined by a method that has less effect on metal structure. It suppress the brittle failure and generation of outgas in a vacuum environment during use. For locations with narrow top space and hex wrench cannot be used. Application Vacuum device / Vacuum container / FPD production device / Semiconductor manufacturing device / Electron microscope Related Service Screw Length Adjustment Service Individual Sales Service
