Kozak Micro Adjusters offers 1/4-80 TPI imperial fine adjustment screws in various diameters, screw lengths, hex drives and more. With over 40 years of experience to our name, we work to provide our customers with the best solutions when it comes to premium adjustment screws.

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 tip, 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, optional knobs and drive types are available, and the thread class exceeds 3A. Check out our 1/4-80 TPI screw product list below to determine what works best for you.

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.

What to Know About Our 1/4-80 TPI Fine Adjustment Screws

When you consider our 1/4-80 TPI fine adjustment screws, there are a couple of factors to keep in mind that will help you determine if they are the best fit for your application.
