• Precision manufacturing consistency meeting ISO 7380-2 standards with Class 6h thread fit for uniform performance

Professional Applications & Engineering Value

These M4 rounded head screws deliver critical engineering solutions where vibration resistance and structural integrity are paramount. The zinc-plated alloy steel construction provides essential corrosion protection for machinery, automotive components, and outdoor equipment. The flanged button head design eliminates washer requirements while providing superior clamping distribution, making them ideal for sheet metal assemblies, electrical enclosures, and structural frameworks. With Class 10.9 strength rating and fully threaded coarse pitch configuration, these metric fasteners ensure rapid installation and reliable performance in high-stress applications. The combination of Rockwell C32 hardness and precise hex drive compatibility prevents stripping during torque application, reducing assembly errors and maintenance downtime in industrial settings.

Specification Summary & Compliance
