Vacuum release screw, also known as exhaust screw or perforated screw, is a screw designed specifically for vacuum systems. Its appearance is almost the same as ordinary screws, the only difference being that the vacuum screw has a through hole along the axis from beginning to end. In a vacuum system, vacuum screws are used, and the gas inside the blind hole is quickly drawn out through the hole in the center of the screw, allowing the system vacuum to reach the target value. We perform precise cleaning and packaging before leaving the factory to ensure the quality of our products.
