The AJS254-0.5H-NL Adjustment Screw has precision cut threads and offers 0.5 in precision travel obtained with hex-head adjustment, intended for use with Newport optical mounts, stages, and most micrometer-compatible components.
With sub-micron sensitivity, they offer an alternative to micrometers where position readout is not required. High-precision 254-TPI, cut stainless steel threads are mated with the collet and a lubricant which reduces the elastic effect allowing accurate movement. The standard 0.375 in diameter collet is threaded with a nut for mounting to optical mounts and stages. KD.37 and KD.75 stainless steel knobs are available as an accessory.
