Our 1/4-100 (100 TPI) ultra-fine adjusters are available in lengths from 5/16" to 4.0", are supplied with a 53 HRC .156" or .187" diameter tip, and provide sub-micron sensitivity. This makes them an ideal alternative to more costly micrometers where position-indicated readout is not a necessity. Our ultra-fine adjusters are HEX driven and optional knobs and drive types are available. Thread class exceeds 3A.

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