【Before】 ■Fully threaded low-profile screws Fully threaded low-profile screws have threads cut all the way down from the male thread neck, and are a commonly used type. However, because they are fully threaded, there is a possibility that the low-profile screws may fall off and get lost when the door or lid of the enclosure is opened. To prevent screws from falling off, additional anti-fall washers or E-rings are required. ↓ 【After】 ■Partially threaded low-profile screws Partially threaded low-profile screws have a shank diameter that is narrower than the screw diameter in the unthreaded section, which allows for the prevention of screw fall-off or loss even when screws installed on doors of various enclosures are removed. *Although they have an anti-fall structure, it is also common to use additional anti-fall washers. *For more details, please refer to the catalog or feel free to contact us.
