Professional Applications & Engineering Value

These zinc-plated steel rounded head screws deliver exceptional value in industrial fastening applications where corrosion resistance and mechanical reliability are critical. The M3 metric thread with coarse 0.5mm pitch and Class 6g precision ensures rapid installation while minimizing the risk of cross-threading in high-volume production environments. The fully threaded design provides maximum engagement across the entire 25mm length, distributing clamping force evenly to prevent joint failure. With 60,000 psi tensile strength and Rockwell B71 hardness, these JIS B 1111 compliant screws maintain integrity under vibration and dynamic loads common in machinery, electrical enclosures, and automotive assemblies. The zinc-plated surface treatment offers essential protection against oxidation in humid or mildly corrosive conditions, extending service life while maintaining RoHS 3 compliance for environmentally conscious manufacturing operations.
