Dual Anti-Corrosion Performance: SS304 Base + Black Zinc Coating
Made of AISI 304 austenitic stainless steel with inherent moisture & rust resistance. The dense black zinc passivation layer further enhances salt spray tolerance, effectively resisting indoor dampness, kitchen & bathroom steam and mild outdoor humidity. No rust peeling or contamination occurs unlike carbon steel screws. The coating fully covers thread gaps for comprehensive protection.
Sleek Matte Black Aesthetic
Uniform matte black finish matches dark-colored equipment, furniture and housings perfectly, reducing glare and delivering a minimalist integrated appearance for exposed installation.
Moderate Toughness, Not Easy to Break or Strip Threads
Excellent ductility of SS304 avoids head fracture and thread stripping under normal tightening torque, durable for long-term vibration scenarios.
RoHS Compliant Eco-Friendly Coating
Trivalent black zinc passivation meets EU RoHS standards, free of harmful hexavalent chromium, qualified for electronic exports.
