High-Tech Manufacturing Powerhouse
To maintain our status as a premier non-standard screw manufacturer, we have heavily invested in two state-of-the-art production bases. Our Dongguan facility spans 8,000 square meters, while our Lechang Technology plant covers 12,000 square meters. These facilities house fully automated workshops dedicated to screws, washers, lathes, nuts, and stamping processes.
- Advanced Cold Heading: Multi-station cold heading machines, three-die six-blow machines, and four-die cold headers capable of producing M1-M22 specifications.
- Precision Threading: High-speed thread rolling and combination thread rolling machines ensuring flawless pitch and engagement.
- Custom Stamping: High-precision stamping machines with continuous dies for parts under 1.0mm, and single punch dies for 3-5mm thickness. Washers, spring pads, flat pads, and square pads are crafted with exactitude.
- CNC Machining Excellence: Walking CNC machines for cylindrical parts and machining centers that control tolerances down to an incredible 2-3 silk (0.02-0.03mm).
- Nut Production: Dedicated nut cold heading machines for M2-M16, and cam machines for knurled and insert nuts.
Backed by a mature supply chain and professional teams across technical, quality, and domestic/international business divisions, we are the definitive experts in non-standard fastener solutions, offering a true one-stop hardware assembly experience.
Zero-Defect Quality Control Laboratory
Positioning ourselves in the mid-to-high-end market requires more than just advanced manufacturing; it demands uncompromising quality assurance. YH FASTENER has established a rigid quality control ecosystem comprising an optical sorting workshop, a full inspection workshop, and a comprehensive state-of-the-art laboratory.
Our optical sorting workshop is equipped with over ten advanced optical sorting machines. These AI-driven systems precisely detect screw dimensions and surface flaws, actively preventing material mixing at speeds exceeding 600 pieces per minute. To guarantee a 100% flawless appearance and product uniformity, our full inspection workshop conducts rigorous visual evaluations.
Every product undergoes severe testing to ensure it meets and exceeds client expectations. Our laboratory is a testament to our commitment to engineering perfection.
