• Full 25mm threading ensures maximum thread contact along the entire length for superior pull-out resistance

Professional Applications & Engineering Value

This M6 metric screw with spring lock washer addresses critical vibration-induced loosening in industrial machinery, automotive assemblies, and electrical enclosures. The 18-8 stainless steel construction combined with passivated finish provides exceptional resistance to corrosion and chemical exposure, making it ideal for outdoor equipment and marine applications. The coarse thread pitch and Class 6g thread fit ensure rapid installation while maintaining precise tolerances in production environments. The integrated lock washer actively counters vibrational forces that typically compromise fastener integrity, delivering reliable performance in demanding industrial applications where maintenance access is limited and failure is not an option.
