High-Performance Vented Screws for UHV & Semiconductor Applications

Are virtual leaks in blind tapped holes slowing down your pump-down times and preventing you from reaching the desired ultra-high vacuum (UHV) level? 

Trapped air and contaminants can be a persistent problem, impacting the efficiency and precision of your semiconductor and vacuum systems.

Our SUS316 and SUS304 stainless steel vented screws are the definitive solution. Also known as vacuum screws, they feature a precision center-drilled vent hole that allows trapped gases to evacuate quickly and completely.

Key Benefits of Our Vented Screws:

Eliminate Virtual Leaks: The core function is to provide an escape path for trapped air and volatiles from the bottom of blind tapped holes.

Achieve Faster Pump-Down: By removing gas pockets, our screws significantly reduce the time required to reach your target vacuum pressure.

UHV/Semiconductor Grade Material: Manufactured from high-quality SUS316 (A4) or SUS304 (A2) stainless steel, featuring excellent corrosion resistance and low outgassing properties essential for cleanroom and UHV environments.
