Features

Designed for Vacuum Applications

Our low outgassing adjustment screws are designed for demanding vacuum environments. Several key steps are taken in the design, assembly and packaging of these parts. We incorporate metals into our designs that are known to be vacuum compatible and desired or approved for use in vacuum systems. In particular, bronze is used in place of brass to eliminate the presence of zinc, which will actually sublimate in a vacuum environment. Following the machining of the screw and bushing, each component is chemically cleaned in an ultrasonic bath to remove contaminating substances. These screws are cleanroom assembled using vacuum compatible lubricants.

Packaged to Avoid Contamination

Low outgassing adjustment screws are packaged in specially-cleaned vacuum-sealed bags, ready for cleanroom and vacuum chamber applications.
