IATF 16949 Certified Automotive Fastener Supplier
Driving Safety, Precision, and Traceability in Global Automotive Supply Chains with AI-Enhanced Manufacturing Solutions.
IATF 16949: The Gold Standard for Automotive Excellence
Ensuring the highest levels of safety compliance and risk management for the modern assembly line.
Safety Compliance
In the automotive industry, a single fastener failure can lead to catastrophic results. Our IATF 16949 certification ensures that every screw, nut, and bolt meets rigorous safety standards required by Tier 1 and Tier 2 suppliers.
Full Traceability
We implement a robust Batch Traceability Label system. From raw material heat codes to final optical inspection, every component has a digital "birth certificate" for complete accountability.
JIT Delivery
Automotive assembly lines operate on Just-In-Time (JIT) principles. Our mature supply chain and dual production bases in Dongguan and Lechang guarantee seamless logistics to prevent line stoppages.
Precision Engineering & Production Power
From M1 to M16, we provide one-stop hardware assembly solutions.
Cold Heading & Threading
Equipped with multi-station cold heading machines (two-mode four, three-mode three, etc.), we produce high-strength screws ranging from M1 to M16. Our automatic screw production workshop ensures high-volume consistency.
CNC Machining & Lathe
Our machining center produces precision customized lathe parts with tolerances as small as 0.006mm. We specialize in knurled nuts, inlay nuts, and complex cylindrical parts.
High-Precision Stamping
With progressive dies, we produce stamping parts from 0.1mm to 5mm in thickness, including elastic pads, flat pads, and square gaskets for automotive electronics.
Dongguan Yuhuang Electronic Technology Co., Ltd. (established in 1998) operates two massive production bases. The Dongguan facility covers 8,000 square meters, while the Lechang Technology base expands across 12,000 square meters. This scale allows us to house dedicated workshops for screws, gaskets, lathes, nuts, and stamping, all integrated into a perfect production chain.
