Professional Applications & Engineering Value

This M5 pan head screw with integrated spring lock washer addresses critical challenges in industrial assembly where vibration-induced loosening compromises equipment reliability. The 18-8 stainless steel core material provides inherent corrosion resistance, while the passivated finish enhances surface durability against chemical exposure. The 410 stainless steel spring lock washer creates constant spring tension that maintains clamp load despite thermal cycling or mechanical vibration. With Class 6g thread tolerance and coarse thread pitch, these metric screws deliver rapid installation in production environments while maintaining precise fit in tapped holes. The combination of 70,000 psi tensile strength and full threading ensures uniform stress distribution, making these fasteners ideal for machinery, electrical enclosures, and automotive components where vibration resistance and corrosion protection are paramount.

Specification Summary & Compliance

This M5 x 0.8mm x 10mm fully threaded screw features Class 6g thread fit per metric standards with coarse thread spacing. Manufacturing complies with ASME B18.13 specifications for dimensional accuracy and performance. The assembly meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring compliance for international industrial applications. Both the screw body and spring lock washer utilize passivated stainless steel finishes for consistent corrosion protection.
