Button head hex socket screws according to ISO 7380-1, manufactured from steel in property class 10.9 with a zinc nickel (ZnNi) coating. The button head features a rounded, raised head profile, while the hex socket provides secure and controlled torque transmission during installation. Zinc nickel coating offers significantly higher corrosion resistance than conventional zinc plating, making these screws suitable for demanding environments requiring long-term corrosion protection. This category includes multiple sizes for machinery, equipment and industrial assemblies where high strength and corrosion resistance are required.
