Brass Plated Small Automotive Lamp Fixing Screw

Brass Plated M3‑M6 Custom Screws for Automotive Lamp Sub‑Unit Fastening Product Overview Automotive lighting manufacturers and retrofit component suppliers often encounter galvanic corrosion risks when mounting fasteners alongside aluminum lamp brackets. Regular steel fasteners in humid environments will trigger electrochemical reaction when touching aluminum alloy, causing pitting corrosion and thread seizure, which greatly raises maintenance difficulty for lamp assemblies. Our cold forming and surface plating customization service produces small metric fasteners ranging from M3, M4, M5 to M6 for lamp assembly applications. We manufacture Brass Plated Lamp Fixing Screw with uniform brass coating to isolate dissimilar metal contact. Each batch of Small Brass Automotive Lamp Bolt undergoes plating adhesion inspection before packing. Our Corrosion Resistant Brass Lamp Screw is engineered to reduce galvanic corrosion between fasteners and aluminum lamp housings in wet working conditions.…
