• Full thread engagement along the entire 10mm length for maximum holding power in various material thicknesses

Professional Applications & Engineering Value

These M4 metric screws with external-tooth lock washers provide critical solutions for vibration-prone industrial equipment and machinery. The combination of 18-8 stainless steel construction and passivated finish delivers exceptional corrosion resistance in harsh environments, while the coarse thread pitch (0.7mm) ensures rapid installation and reliable performance in various substrates. The integrated 410 stainless steel lock washer with external teeth bites into mating surfaces, preventing loosening under dynamic loads - making these rounded head screws ideal for automotive assemblies, electrical enclosures, and manufacturing equipment where vibration resistance and long-term reliability are paramount. The Phillips drive design facilitates efficient installation while the pan head profile provides excellent bearing surface for secure fastening.
