Vented screws allow trapped gases to escape while under vacuum.
This page features vacuum-compatible versions of our most popular screws. These screws are fabricated from specially selected grades of stainless steel and aluminum for vacuum and cleanroom use. All components are packaged in double airtight bags for cleanroom and vacuum chamber applications. The cross section of a vented screw to the right illustrates the benefits of vented screws when used within a vacuum chamber. We also offer standard cap screws and setscrews in a variety of sizes.
Vacuum Compatibility Information
We also offer other optomechanical components which may be used in vacuum applications. Many of our Polaris™ Mirror Mounts are vacuum compatible. We also offer Unanodized Aluminum or Passivated Stainless Steel Breadboards, which may be used in vacuum applications after undergoing cleaning and processing by the end user.
Vacuum Compatibility Specs
The TS25HV and TS6HV/M are 1/4"-20 or M6 x 1.0-threaded for compatibility with our imperial or metric Vacuum-Compatible Ø1/2" Post Holders, respectively. Please note that we do not recommend using an L wrench hex key to tighten these thumbscrews, as this may break off the screw head. The recommended maximum torque is 28 in·lbs (3.2 N·m). We also offer standard spring-loaded thumbscrews.
