Custom Vacuum Screws
Custom Vacuum Screws | Precision Aluminum & Stainless Steel Fasteners
Product Overview
Our vacuum screws are designed for high cleanliness, precise machining, and low outgassing performance.
Each screw features centered through holes at both ends and in the middle, ensuring perfect alignment without eccentricity.
All parts are carefully deburred and finished to meet the strict requirements of vacuum and cleanroom applications.
Ideal for vacuum chambers, semiconductor equipment, optical instruments, and laboratory devices.
Material Options
Aluminum Alloy (6061-T4 / 6061-T6 / 7075-T6) – lightweight, strong, corrosion-resistant
Stainless Steel (304 / 316L) – durable and stable in high-vacuum environments
Other materials available on request: Brass, Titanium, Inconel, and more
