Our 1/4-80 (80 TPI) fine adjusters are available in lengths from 5/16" to 4.0" 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. Our 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.
