Our 1/4-80 TPI adjustment screws are available in lengths from 5/16" to 4.0", are supplied with a 53 HRC .156" or .187" diameter tips, and provide sub-micron sensitivity. This makes them an ideal alternative to more costly micrometers where the position-indicated readout is not a necessity. Our fine adjusters are HEX-driven, and optional knobs and drive types are available. The thread class exceeds 3A.

Note: Kozak Micro Adjusters cannot guarantee that our screws and bushings will be compatible with screws and bushings sold by other manufacturers. Learn more about our 1/4-80 TPI screws today.
