Under New York City's strict Local Law 97 and energy-conservation building mandates, exterior thermal envelopes rely heavily on uPVC insulated glazing systems, thermal breaks, and architectural polymeric panels. OEM self-tapping screws engineered with optimized Hi-Lo thread designs provide superior strip-out resistance in hollow and cellular PVC framing, eliminating structural micro-fissures during rapid field installation across Manhattan and Brooklyn developments.
From Long Island coastal industrial facilities to New York Harbor maritime terminals, standard fasteners fail prematurely from galvanic corrosion and chloride exposure. Our factory produces custom 304 and 316 austenitic stainless steel and zinc-nickel alloy self-tapping fasteners that guarantee over 1,000 hours of ASTM B117 salt spray endurance, ensuring structural integrity for exterior PVC siding, conduit clamps, and marine junction units.
Modular construction is booming across Upstate New York (Buffalo, Rochester, Albany) and NYC borough prefab developments. Automated pneumatic and robotic assembly lines require high-precision OEM fasteners with consistent shank straightness, clean thread-forming flutes, and calibrated drive recesses (Phillips, Torx, Pozi) to minimize downtime, cam-out damage, and material cracking.

Starting with a single screw, Su Yuqiang spent thirty years transforming "Yuhuang" into a reliable brand in the field of hardware manufacturing, and himself became the recognized "Screw Prince" in the industry.
Starting from scratch, he lacked funds and equipment in the early stage of his entrepreneurship, but always engraved "customer needs" in his heart. Once an American customer requested a non-standard screw, many factories failed in their trials. Su Yuqiang didn't give up: repeatedly adjusting the molds, sending samples at his own expense, once, twice... Finally, on the fifth attempt, he successfully produced a product that met the requirements. This meticulousness and persistence earned him the trust and cooperation of customers for over twenty years.
After thirty years of deep dedication, Su Yuqiang, with the belief of "tenacity and pragmatism, service first", led Yuhuang to move forward steadily; his diligence and commitment as a public servant have become benchmarks in the industry, and "centering on customers" has become the core development philosophy engraved in the bones of Yuhuang.






We supply Hi-Lo dual thread configurations, Type AB tapping threads, and specialized thread-forming points. The 30° sharp high-thread cuts cleanly into hard vinyl and composite PVC without creating radial pressure spikes, while the 60° low-thread compacts material to prevent loosening under dynamic vibrations.
Available in AISI 304, 316, 410 heat-treated martensitic steel, carbon steel 1022A, and brass. Finish coatings include Ruspert 500-1500 Hrs, Zinc Flake (Geomet/Dacromet), Black Oxide, White Zinc, and fluoropolymer coatings for extreme acid-rain and urban atmosphere resilience in the NY area.
Pan Head, Countersunk Flat Head, Truss Head, Hex Washer Head, and Wafer Head. Recess types include Phillips, Torx (Star) with security pin, Square drive (Robertson), Slotted, and Combo drives configured to ANSI/ASME B18.6.3 and DIN 7981 / 7982 / 7504 standards.
Relying on the entire process manufacturing capabilities and strict quality control, we provide high-quality customized products and full-cycle services for screws, wrenches, and positioning beads to global customers. Centered on customer needs, we continuously create value and strive to become a reliable partner in the hardware manufacturing field.
Offer precise selection suggestions and torque calculation models based on New York application scenarios and material pairing.
Support standard and non-standard drawing customization, with full process follow-up from mold design to sample trial and mass production.
Full process quality control under IATF16949 & ISO9001 systems to ensure fasteners meet rigorous North American certification standards.
Professional technical support, rapid response to customer inquiries, and seamless logistics coordination direct to New York facilities.







A: PVC is sensitive to localized hoop stress which can cause micro-cracking and boss splitting. Our OEM PVC screws feature custom thread angles (such as 30°/60° Hi-Lo threads) and specialized flute geometry that cleanly slices and channels polymer chips away rather than aggressively wedging the plastic. This ensures high pull-out retention and prevents thread strip-out during automated assembly.
A: Yes. All our fastener batches are compliant with RoHS and REACH standards. We manufacture under ISO9001 and IATF16949 quality management systems, providing material test reports (MTR), full chemical spectrometry, tensile test certificates, and salt-spray test documentation required by New York engineering inspectors.
A: Standard catalog items and existing tooling samples can be dispatched within 2-4 business days. For custom OEM drawing requirements, mold fabrication and prototype sampling take approximately 7-12 days, followed by sea freight (via Port of New York & New Jersey) or expedited air freight direct to JFK/EWR.
A: We offer integrated EPDM vulcanized sealing washers, nylon insulating collars, and specialized barrier coatings (organic Ruspert, Geomet, or PTFE). These solutions completely isolate dissimilar metals, preventing electrolytic reaction even in high-humidity coastal and industrial atmospheres across the New York region.
