Eliminate Virtual Leaks with a Vented Screw for HV & UHV Systems

Shop Screws

UC Components, Inc. is the premier manufacturer of vented screws and fasteners for High Vacuum and Ultra High Vacuum equipment and other clean-critical applications. Our RediVac® screws are designed to provide complete evacuation of trapped volumes of air during pump-down and eliminate “virtual leaks.”

Our vented screws are available with center or slot (side) vents. Both vent types offer effective venting in any HV or UHV application. UC offers both inch and metric screw sizes, as well as non-vented screws for through-holes in HV and UHV systems and other applications.

Sizes & Styles

Our vented and non-vented screws are available in a wide range of sizes and lengths; along with a myriad of custom configurations and options. We also offer a large selection of head styles, making it easy to find the right one for your particular installation requirements. See individual product listings for additional size and head style information.

Our inch-measure screws are manufactured to meet ASME standards. Our metric-measure screws are manufactured to meet DIN and ISO standards.

Materials & Finishes

All UC Components, Inc. parts are precision cleaned and packaged in our certified Class 100/ISO Class 5 Cleanroom prior to shipment; which means that our RediVac® products are ready for immediate vacuum service. We offer a variety of vacuum-stable specialty finishes (including WS₂ and MoS₂ coatings, gold, silver, and nickel) to help boost system performance, reduce corrosion, and prevent galling.

If you can’t find vented or non-vented screws in the right size, length, material, finish, or head style for your need, please contact us. We carry many more products in addition to the ones listed in our standard catalog.
