Introducing "Fine Passivate," a high-density non-conductive surface treatment that forms a meticulous oxidation-resistant coating even on SUS410. By optimizing the passivation treatment, a non-conductive coating with a higher chromium content than conventional treatments is formed on the screw surface. The high-density non-conductive coating is stronger than typical passivation and thoroughly protects the screw surface from corrosion factors. 【Features】 ■ Made from standard SUS410, ensuring strength and properties are the same as conventional treatments ■ Achieves 1000 hours in salt spray testing without special coating treatment (according to Osaka Prefectural Industrial Technology Research Institute, test request number Heisei 26-02-02549) ■ Thorough quality control with in-house passivation treatment facilities *For more details, please refer to the PDF document or feel free to contact us.

When using a standard drill screw on aluminum, the chips become long, which can lead to them getting caught during construction and can cause unexpected injuries. Al-Drive is a drill screw with a special cutting edge that cuts and breaks up the chips to prevent them from getting caught. It is targeted for aluminum sash construction and is available in four colors—silver, gold, bronze, and black—to match the color of the sash. Of course, it can also be used on steel materials other than aluminum sashes.

It is often the case that ordinary screws cannot penetrate or fit properly. This drill screw is ideal for the cabal roof method (a construction technique that involves covering a slate roof with a metal roof). By sharpening the tip, it can penetrate even hard slate that would typically cause the tip of a regular drill screw to chip. The head is a special bind head that securely holds the metal roof while ensuring a good grip for the bit. The screw section is a coarse screw that firmly grips the sheathing board. With a custom shape from the head of the screw to the tip, this drill screw makes the cabal roof method significantly easier.

SUS410 screws have the disadvantage of being difficult to form an oxidation-resistant coating on their surface due to the low amount of chromium in the material and the reduction of chromium in the surface hardening layer caused by heat treatment. KM Seiko has developed Fine Passivation, which forms a dense oxidation-resistant coating even on SUS410. 【Features】 ■ The material is standard SUS410, so strength and physical properties are the same as before. ■ Achieved 1000 hours in salt spray testing without special coating treatment (tested and confirmed at the Osaka Prefectural Institute of Industrial Technology). ■ Thorough quality control with in-house passivation treatment equipment. *For more details, please request materials or view the PDF data available for download.
