In the contemporary construction landscape, Roofing Tek Screws (also known as self-drilling screws) have evolved from simple fasteners into highly engineered components critical for structural integrity. As buildings face more extreme weather patterns—ranging from high-velocity hurricanes to intense thermal cycling—the demand for Custom Roofing Tek Screws has surged. Modern roofing systems in commercial and industrial sectors now require fasteners that do more than just hold materials together; they must provide electrolytic corrosion resistance, superior pull-out strength, and airtight sealing.
Zhejiang Jifeilong Instrument Technology Co., LTD., leveraging decades of expertise in high-precision electrical and hardware manufacturing, addresses this global need. By integrating ISO9001 certified quality controls with advanced metallurgical techniques, we provide the global market with Tek screws that exceed standard ASTM and DIN specifications.
At Zhejiang Jifeilong, we have transitioned from traditional manufacturing to an "Industry 4.0" model, ensuring our global partners receive consistent quality with unmatched lead times.
Utilizing high-speed cold heading and thread rolling machines that eliminate human error, ensuring every Tek screw meets exact dimensional tolerances.
From raw material spectroscopy to salt spray testing and torque analysis, our QC department ensures compliance with international safety standards.
Located near the Oujiang Port in Wenzhou, we leverage a robust logistics network to offer express shipping and streamlined customs clearance for international buyers.
For large-span steel structures, our Tek screws with EPDM washers ensure a 100% waterproof seal and rapid installation, reducing labor costs by up to 30%.
Specialized stainless steel (SS410/304) and bi-metal screws designed to resist atmospheric salinity and chemical oxidation in industrial zones.
Fasteners with higher drill-point grades (Type 4 or 5) capable of penetrating thick structural steel (up to 12.5mm) without pre-drilling.
Zhejiang Jifeilong Instrument Technology Co., LTD. (formerly Yueqing Feilong Instrument Factory) was established in September 1999. Our journey from a local workshop to a high-quality global supplier of components is built on the tenet of "seeking truth from facts and quality first."
Our expertise extends across electrical switches, shafts, and hardware components used in home appliances, automobiles, and filtration equipment. This cross-industry experience allows us to bring a higher level of precision to the manufacturing of Roofing Tek Screws than traditional fastener-only factories.
"Operate With Integrity And Achieve Multi-Party Win-Win. Reputation Supreme, People-Oriented, Quality As The Root."
Tek screws feature a built-in drill point that allows for one-step installation. This eliminates the need for separate drilling, tapping, and fastening operations, significantly increasing efficiency in industrial metal roofing applications.
We utilize multi-stage coating processes, including mechanical galvanizing and organic polymer coatings. Our products undergo salt spray testing (up to 2000 hours) to ensure they meet the requirements of C3 and C4 corrosive environments.
Yes. As a factory-direct manufacturer, our expert engineering team provides tailored design services. We can customize thread pitch, head style (hex, flange, wafer), and drill point length based on the specific gauge of steel being used in your project.
Standard orders are processed and shipped within 3 to 5 days due to our fully automated production capacity. Custom OEM designs typically require 2-3 weeks for sample validation and mass production.
Strict QC protocols at every stage—from raw material procurement to final shipping—adhering to international quality standards.
24/7 Support: Our professional team is available 24 hours a day to provide technical consultations for global clients.
As a direct manufacturer, we eliminate the middleman, offering streamlined supply chain management and high operational efficiency.
