Engineered for extreme tensile strength (≥895 MPa), weight reduction (-44% vs steel), and total immunity to road salt, brake fluid, and thermal corrosion.
As a premier onsite-verified manufacturer, Zunvo Titanium Products Co., Ltd. operates at the epicenter of world-class titanium processing in the Shiling Road Industrial Park, Baoji City, Shaanxi Province. Founded in 2015, our specialized production floor spans over 3,000 square meters, backed by an elite engineering force of 101 to 200 manufacturing experts dedicated exclusively to non-ferrous hardware fabrication.
Our strategic position within China's "Titanium Valley" provides direct access to primary vacuum arc remelting (VAR) titanium sponge ingots and certified Grade 5 bar stock. Every manufacturing lot is fully traceable back to its original mill heat number, guaranteeing complete elimination of material impurities or sub-standard titanium alloys.
"Combining state-of-the-art multi-axis CNC Swiss turning centers, automated hot-heading presses, and precision thread-rolling machinery, Zunvo bridges the gap between aerospace-grade manufacturing standards and commercial OEM/ODM scalability."
Whether you require standard DIN 912 socket head screws, DIN 6921 hex flange bolts, or fully customized 3D-modeled parts for motorcycle modification, high-end bicycles, automotive wheel hubs, or marine hydraulics, Zunvo delivers zero-defect manufacturing with full material test certificate (MTC) compliance under EN 10204 3.1 standards.
From micro-grain metallurgical structure to exact electrochemical color matching, discover how our technical advantages drive bottom-line competitive edges for international distributors and brand owners.
Instead of single-point cutting threads which disrupt grain flow, Zunvo utilizes continuous thread-rolling dies after precision hot-heading. This preserves unbroken internal grain boundary flows, boosting thread shear strength and fatigue resistance by over 300% under severe vibration environments.
We offer voltage-controlled electrochemical anodic oxidation providing vivid rainbow, gold, electric blue, purple, and green hues without adding dimensional thickness. For high-wear applications, our Physical Vapor Deposition (PVD) line coats hardware in DLC (Diamond-Like Carbon), TiN, or TiCN for supreme scratch resistance.
Our engineering team reviews STEP, IGES, or DWG drawings within 24 hours. Utilizing high-precision CNC centers operating at ±0.005 mm tolerances, functional prototypes can be produced, anodized, and dispatched via express air freight within 3 business days for rapid fit verification.
Every batch undergoes rigorous quality testing using optical projectors, thread ring/plug gauges (Class 6g / 6H standards), tensile pull testing, and spectrographic material analysis. We maintain a zero-defect shipping record across North America, Europe, and Southeast Asia.
To accommodate aftermarket performance brands and niche engineering firms, custom production runs start as low as 100 pieces per drawing. We support laser-engraved custom logos, bespoke part numbering, and custom retail blister or anti-static packaging solutions.
With integrated door-to-door express logistics (DHL, FedEx, UPS), air cargo, and ocean shipping options, we manage export customs clearance and deliver directly to your assembly line or distribution hub, ensuring seamless supply continuity.

The global demand for high-performance titanium alloy hardware is accelerating driven by automotive electrification, lightweight powersports engineering, drone robotics, and harsh-environment marine systems. Procurement officers and supply chain directors should account for four major industry shifts over the next decade:
1. Electrification and Mass-Reduction Mandates (EV & E-Powersports): As EV manufacturers and electric motorcycle brands seek to extend battery range, reducing unsprung mass at wheel hubs, brake calipers, and suspension linkages has become paramount. Substituting Grade 5 titanium bolts for traditional steel fasteners cuts joint mass by 44% without sacrificing clamping force or fatigue life.
2. PVD Functional & Aesthetic Surface Customization: Modern consumer markets demand both technical performance and visual brand distinction. Physical Vapor Deposition (PVD) coatings—such as DLC Black, Titanium Nitride Gold, and Titanium Carbonitride Violet—are rapidly overtaking standard painting or soft anodizing. PVD provides a thin (1-3 micron) wear-resistant ceramic layer that prevents thread galling while maintaining exact thread tolerances.
3. Closed-Loop Material Traceability and ESG Compliance: Global tier-1 buyers increasingly require verified material heat numbers, conflict-free raw material certifications, and eco-friendly manufacturing processes. Suppliers operating integrated facilities in industrial hubs like Baoji are better positioned to guarantee complete raw material documentation and carbon-efficient production cycles.
4. Shift Towards Custom Geometry & Integrated Flange Drives: Standard off-the-shelf socket head cap screws are being replaced by custom-engineered Torx-drive flange bolts, captive washer designs, and hollow-core weight-saving shafts. Torx (hexalobular) drives distribute installation torque evenly, drastically reducing tool wear and slippage during high-speed automated assembly lines.
A primary historical challenge in titanium fastening was thread galling under high-torque dynamic loads. At Zunvo, our product development team has pioneered advanced multi-layer surface treatment technology that overcomes friction challenges while providing striking aesthetic choices:
Electrochemical Anodizing Technology: By immersing cleaned Grade 5 titanium bolts into an electrolytic bath and applying controlled direct current voltages (from 15V to 110V), controlled titanium oxide (TiO2) microscopic layers are grown on the metal surface. Through light wave refraction, vibrant permanent colors—including Burnt Blue, Purple, Rose Gold, Emerald Green, and Rainbow Oxide—are produced without any chemical dyes or toxic heavy metals.
Anti-Galling Micro-Arc Oxidation (MAO): For critical structural positions requiring repeated disassembly, our Micro-Arc Oxidation process forms a ceramic-like plasma oxide matrix that dramatically reduces the friction coefficient, completely eliminating thread seizing when paired with anti-seize paste or specialized thread coatings.

Grade 5 (Ti-6Al-4V) is an alpha-beta alloy heat-treated to achieve minimum tensile strengths of 895–1,000 MPa, making it structurally comparable to Class 10.9 and Class 12.9 alloy steel bolts. In contrast, Grade 2 is commercially pure titanium with significantly lower tensile strength (~345 MPa), suitable only for non-structural, corrosion-resistant fluid lines or light trim panel fasteners.
Yes. Grade 5 titanium bolts provide exceptional shear and fatigue resistance, making them ideal for rotor discs, brake calipers, and sprocket mounts. When replacing OEM steel hardware, apply a light coat of copper or nickel anti-seize lubricant on the threads and torque to the manufacturer's recommended service manual specifications.
Electrochemical anodizing creates an integrated oxide film that will not chip or peel; however, severe tool abrasion can lighten the oxide layer over time. PVD (Physical Vapor Deposition) applies a hard metallic ceramic coating (such as TiN or DLC) that penetrates the surface, offering superior wear resistance and hardness up to 2,500 HV, ideal for high-impact hex heads or lug nuts.
We accept 3D CAD files in STEP, STP, IGES, or X_T formats, as well as 2D PDF technical drawings with thread specifications, dimensional tolerances, and surface finish requirements. If drawings are unavailable, you can ship a physical sample directly to our Baoji facility for CMM scanning and reverse engineering.
For standard catalog hardware (such as DIN 912 socket bolts or standard metric hex flange bolts), the minimum order is typically 100 to 200 dozens. For custom drawing-based parts or specialized color anodizing runs, our factory accommodates low flexible MOQs starting at just 100 pieces to facilitate prototype validation and market testing.
In-stock hardware ships within 24 hours. Custom sample prototypes are ready in 3 to 5 business days. Mass production batch orders typically require 7 to 15 calendar days depending on color finishing complexity. We ship door-to-door globally via DHL, FedEx, UPS, air freight, or sea cargo with full export documentation.
Yes. Every shipment includes a official EN 10204 3.1 Mill Test Certificate detailing chemical composition (Ti, Al, V, Fe, C, N, H, O content) and physical mechanical test results (tensile, yield, elongation). Additional third-party SGS or TÜV test reports are available upon buyer request.
