At Kozak Micro Adjusters, we offer a variety of thread-per-inch screws, also known as TPI screws. When dealing with precision measurement, TPI is the count of the number of threads per inch that is measured along the length of a fastener. When looking directly at a screw, you are able to distinctly see and count the number of threads. TPI screws with a higher thread count means that they are smaller fasteners that contain finer threads. Screws that have finer threads are known for being stronger in tension. 

Threads per inch is a little different than thread pitch. When searching for your perfect screw, this is something to pay close attention to. Threads per inch is used only with American fasteners compared to thread pitch which is used with metric fasteners.

Something to notice when looking at thread pitch, is that when fasteners have a lower thread pitch, they have a finer thread, which is opposite when comparing to the TPI thread count. When it comes to finding the correct threads per inch for your project, we have the selection for you.
