Who is YH FASTENER (Yuhuang Electronic)?
Established in 1998, Dongguan Yuhuang Electronic Technology Co., Ltd. is a leading industry-and-trade integrated enterprise specializing in the R&D, production, and sales of high-precision fasteners. We have evolved from a standard parts manufacturer into a world-class non-standard fastener solution expert.
With two massive production bases—Dongguan Yuhuang (8,000 sqm) and Lechang Technology (12,000 sqm)—we operate a complete supply chain including automated screw workshops, gasket workshops, lathe workshops, nut workshops, and stamping workshops.
Non-Standard Screw Specialist: Solving Assembly Challenges
Complex Geometry Design
Standard screws often fail in compact or innovative product designs. We specialize in M1-M22 non-standard fasteners with unique head shapes, thread pitches, and drive types to fit your specific assembly constraints.
Material & Environment Compatibility
Facing corrosion or high-stress issues? We provide material analysis and customized plating solutions (RoHS/REACH compliant) to ensure your assembly lasts in the harshest environments.
Automated Assembly Optimization
Our screws are engineered for high-speed automated production lines. With precision tolerances of 2-3 wires (0.02-0.03mm), we eliminate jamming and cross-threading issues for our clients.
