Stainless steel (black dye processing) + small plate screw
This is a small screw with a flat top and a conical-shaped seat that has a cross hole. It is made of iron and has a high corrosion-resistant black coating (Sabinai-jan). It is used when you do not want the head of the screw to protrude. It is necessary to perform counterboring on the material being tightened. It complies with EU-RoHS2 standards.
- High corrosion-resistant black coating (Sabinai-jan) refers to a black-coated stainless steel that forms a black film on the surface of the metal, providing high corrosion resistance. In rust resistance durability tests (salt spray), the typical black coating lasts for 72 hours, while the high corrosion-resistant black coating (Sabinai-jan) exceeds 3000 hours. It is suitable for outdoor use and may be used for salt damage prevention in coastal areas and snow removal regions.
