Electronics & Appliances
Electronics hate three things — stripped micro screws, magnetic interference and post-soldering failures. Generic zinc-plated carbon-steel fasteners cause handheld-device rust, fail RoHS and jeopardise EMC certification. High-density server and optical-module assembly is even trickier: dozens of M2–M3 screws go into a 1U chassis one by one, and inconsistent torque cracks PCBs or starves heatsink contact until the chip overheats, while unstable nickel-plated contact resistance breaks EMI-shield and earthing paths — and a humid Hong Kong plant can rust a whole batch of parts. JIALI supplies 304 / 316 stainless micro screws M1–M3 (GB/T 818, ISO 7380, GB/T 832-838), brass set screws and self-tapping screws with non-magnetic passivation, silver plating and zinc-nickel finishing, plus tray-pack supply, incoming inspection and batch traceability — a reliable Hong Kong supplier of micro screws for electronics & appliances and fasteners for server chassis.
