Bolt with hexagonal head SVHS

stainless steel

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.
