The HVAC industry is pivoting toward high-velocity airflow and airtight ducting. This shift demands sheet metal screws with superior "self-piercing" tips and specialized coatings like Zinc-Nickel to prevent galvanic corrosion in high-humidity environments.
Modern procurement directors are moving beyond "unit cost." They now prioritize "In-place Cost" and "Total Cost of Ownership (TCO)," seeking suppliers who offer automated sorting and zero-defect consistency to prevent line stoppages.
China's manufacturing heartland has transitioned to Factory 4.0. Utilizing AI-driven optical sorting and real-time production monitoring, suppliers like Zhejiang Jifeilong ensure that every fastener meets exacting aerodynamic and structural standards.
In the complex architecture of modern commercial and industrial HVAC systems, the humble sheet metal screw is a critical failure point or a silent enabler of efficiency. As a leading China HVAC Sheet Metal Screws Supplier, we understand that these components must withstand thermal expansion, vibration, and corrosive condensates for decades.
Established in September 1999 (formerly Yueqing Feilong Instrument Factory), Zhejiang Jifeilong Instrument Technology Co., LTD. has evolved into a powerhouse of precision manufacturing. Located at the Oujiang Port in Wenzhou City, our facility integrates production, grinding, and automated assembly to serve the global hardware market.
We adhere to "Seeking truth from facts and quality first." Our vision is to be a high-quality global supplier of components, upholding the spirit of "People-oriented, and quality as the root."
By implementing strict quality control in every production link—from raw material procurement to finished product delivery—the company has proudly passed the ISO9001 certification.
Through technological and equipment transformation, we have achieved fully automated production capacity, serving over 100 enterprise customers with unparalleled reliability.
We utilize specialized carbon steel and stainless steel alloys (304/316) that provide the optimal balance of tensile strength and ductility. For HVAC applications, our screws undergo a proprietary heat-treatment process to ensure the tips remain sharp enough to pierce metal without snapping under high torque.
Condensation is the enemy of ductwork. Our "Blue-Zinc" and "Yellow-Zinc" electroplating, along with advanced Dacromet coatings, offer superior protection against the micro-climates found inside air handling units and evaporative coolers.
Our expert engineering team provides tailored design services. From custom thread pitches to unique head styles (Pan, Hex, Washer, or Truss), we offer free samples to ensure our products meet your exact engineering specifications before mass production.
A: High-adaptability screws feature a precision-engineered "leading thread" that engages immediately with sheet metal. This reduces "wandering" during installation, protecting the surface finish and ensuring a tighter seal.
A: We use a multi-stage QC process: 1. Raw material chemical analysis. 2. Real-time sensor monitoring during cold heading. 3. Final automated optical sorting to remove any fastener with a dimensional deviation exceeding 0.01mm.
A: Absolutely. Our expansion into the NEV sector—providing pins, shafts, and connectors—demonstrates the versatility of our hardware. The same precision required for MCCBs (Molded Case Circuit Breakers) is applied to our HVAC fasteners.
A: Leveraging our proximity to Oujiang Port, standard orders are processed within 3-5 days. For custom OEM designs, we provide prototypes within 7 days and mass production typically within 15-21 days.
