Boosting Vacuum System Performance: Materials and Selection Guide for Vented Screws
Vented Screws: A Key Component to Enhance Vacuum System Performance
In high-precision vacuum applications such as semiconductor manufacturing, optical instruments, cleanroom environments, and food processing equipment, maintaining a stable and efficient vacuum is crucial.
However, traditional screws can trap air between the screw tip and the bottom of a blind hole, making it difficult to achieve the desired vacuum level during evacuation.
Vented screws—also known as vacuum or through-hole screws—were developed to solve this problem.
What Are Vented Screws?
Vented screws look like standard screws but feature a unique design: a hole running through the center of the screw or a flat milled side.
This allows trapped gases to escape quickly during vacuuming, significantly improving the system’s evacuation efficiency and enabling the vacuum chamber to reach its optimal performance faster.
Conclusion
Though they may appear ordinary, vented screws play a crucial role in the efficiency and reliability of vacuum systems. In fields that demand precision and contamination-free environments, using the right vented screw can make all the difference in system performance and operational stability.
