We were granted a patent for the invention of the “loose-stop screw”.

In November 2018, we were awarded a patent for the invention of a “loose-stop screw”. This patent was applied for by our in-house training instructors, who are experts in their field, and this product is an anti-loosening screw that can be used repeatedly and still be effective. There are various ways to prevent loosening, such as applying the anti-loosening agent by secondary processing, not only for this product, but also for the product itself, so please contact us using the inquiry form on our website.
