1/4-100 TPI High-Vacuum Screws

Check up to five results to perform an action.

Our 1/4-100 (100 TPI) high-vacuum compatible fine adjusters are available in lengths from 3/8" to 2.0" and are supplied with a 53 HRC .156" or .187" dia. tip and provide sub-micron sensitivity making them an ideal alternative to more costly micrometers where position indicated readout is not a necessity. The screws are made of 304 SS and are supplied with a ball tip (53 HRC) made of hardened steel. The screws are passivated and include a relief in the ball cavity which allows air to escape from under the ball-tip. Our fine adjusters are HEX driven and optional knobs and drive types are available. Thread class exceeds 3A. Additional lengths available by request.

Note: Kozak Micro cannot guarantee that our screws and bushings will be compatible with screws and bushings sold by other manufacturers.
