Miniaturized Lead Screws

Extremely small micro lead screws built for precision applications. These lead screws support applications where accuracy, precision, and miniaturization are a must, with screw diameters ranging from 4.0mm all the way down to 0.5mm!

Lead screws sized down to half a milimeter in diameter!

Micro Lead Screws

Micro lead screw sizes range from 0.5mm to 4.0mm. These incredibly small nut and lead screw assemblies can therefore connect to highly compact units. Thus, they excel at saving size and weight. We focus on small sized screws but can support additional sizes upon request.


We’ve successfully tested these micro lead screws over 80km (50 miles) under continuous load of 2.5kg. Furthermore, our synthetic resin nut and 3mm screw can endure over 900N when break tested. As a result, these lead screws can be trusted for critical precision applications and measuring instruments.

Positional Accuracy

Our synthetic resin nut combined with grinding screw makes for a backlash under 2μm! Consequently, these screws have a high degree of positional accuracy by design. In addition, lead screws are processed and assembled using our own exclusive technology to further ensure accuracy and precision.
