Fine Adjustment Screws from Kozak Micro Adjusters

For all of our adjustment screws listed above, please note that Kozak Micro cannot guarantee that our screws and bushings will be compatible with screws and bushings sold by other manufacturers.

Also, in addition to our fine adjustment screws and variety of imperial screw sizes, we do offer bulk custom orders that are tailored to your exact specifications.

Understanding Which Adjustment Screws to Use in Your Application

 If you are trying to distinguish between fine adjustment screws and ultra-fine adjustment screws for your project, or need reassurance that you are purchasing the right product, we can help.

The most obvious difference between the two is their thread counts. Ultra-fine adjustment screws have more threads per inch, coming in with a total of 100-500 TPI. Meanwhile, fine adjustment screws have between 40-100 TPI, making them ideal for applications where precision is required but there is a relatively large travel distance.

Therefore, it is important to note the purpose of your application and the threads per inch needed when deciding between the two. For more information on the differences between fine adjustment and ultra-fine adjustment screws, be sure to check out our comparison post.
