Automotive Parts

Automotive joints face constant vibration, heat and alternating loads, and a loosened or fatigue-fractured fastener directly threatens driving safety. Lightweighting brings its own traps — aluminium housings mixed with high-strength steel parts invite galvanic corrosion at flange faces, plastic brackets strip when over-torqued, electroplated 10.9+ bolts need hydrogen-embrittlement relief against delayed fracture, nylon lock nuts heat-soften in engine-bay hot zones, and repeated servicing keeps eroding clamping torque. JIALI supplies 10.9 / 12.9 grade high-strength bolts (post-plate hydrogen baking, Dacromet preferred for high-strength parts), flange and nylon locking nuts, anti-strip washers, and drawing-based custom EV fastening solutions; hot zones run all-metal lock nuts (GB/T 6184) with high-temperature coatings, with torque-to-angle assembly and friction control per ISO 16047 supported — all to IATF16949 quality requirements with PPAP documentation and batch traceability, a reliable Hong Kong partner for automotive parts fasteners.
