Category: Hex Head Vented Screw DIN933

Vented Screws, also recognized as Vacuum Screws, Ventilation Screws, or Hollow Screws, possess a hollow core with a drilled hole. Specifically engineered to facilitate the release of gases, contaminants, and pressure through the fastener, these screws are extensively employed in vacuum systems. They play a crucial role in expediting the pump-down process of HV, UHV, and EUV systems, ensuring swift evacuation of trapped air pockets and surface contaminants from blind-tapped holes.

This not only accelerates the pump-down of a vacuum system but also eliminates “virtual leaks.” Trapped air can potentially contaminate a vacuum system, and the faster pump-down and contamination elimination lead to increased throughput and enhanced yield.

These vented screws serve a purpose in systems that necessitate controlled gas or fluid flow to maintain equilibrium. Industries such as manufacturing, automotive, aerospace, and instrumentation leverage vented screws to optimize operational efficiency and safeguard sensitive components from pressure-related challenges.
