OEM/ODM Titanium Wheel Studs Supplier & Precision Racing Fasteners

For safety-critical structural joints like wheel studs, brake caliper mounts, and steering knuckles, Grade 5 Ti-6Al-4V (also denoted as TC4) is mandatory. Commercially Pure (CP) Grade 2 titanium possesses a tensile strength of roughly 345–450 MPa, which is entirely insufficient for the cyclical shear, clamping, and bending loads experienced at the hub. Grade 5 is an alpha-beta alloy containing 6% aluminum and 4% vanadium, delivering minimum tensile strengths of 895–1050 MPa and yield strengths above 828 MPa, mirroring the mechanical capabilities of high-tensile Class 10.9 structural automotive steel bolts while cutting mass by 44%.

Galling (cold welding) is a known phenomenon when identical passive metals rub under dry high-pressure contact. Velnora mitigates galling through three rigorous engineering practices: First, our threads are cold-rolled to achieve an ultra-smooth surface finish ($Ra \le 0.4 \mu m$), eliminating microscopic asperities. Second, we offer specialized Physical Vapor Deposition (PVD) surface treatments like DLC (Diamond-Like Carbon), TiN, or Type II electrolytic anodizing, which alters surface hardness and friction coefficients. Third, we specify and supply compatible high-pressure molybdenum disulfide or copper-free anti-seize lubricants with adjusted torque-tension calculation factors ($K$-factor of 0.12–0.15) for flawless, repeatable torquing cycles.

Yes. Grade 5 titanium exhibits exceptional thermal stability up to +400°C to +450°C without significant phase transformation or reduction in tensile yield strength. In fact, titanium has a notably lower coefficient of thermal conductivity ($\approx 6.7 \text{ W/m}\cdot\text{K}$) compared to chrome-moly steel ($\approx 42 \text{ W/m}\cdot\text{K}$) and aluminum ($\approx 130 \text{ W/m}\cdot\text{K}$). This property acts as a thermal barrier, limiting the transfer of dangerous brake disc heat into wheel bearings, hub grease, and sensitive wheel center seals during prolonged track sessions.

Because titanium has a modulus of elasticity approximately half that of steel (114 GPa vs. 210 GPa), titanium fasteners stretch more elastically at a given load, storing clamping energy effectively. When installing Gr5 titanium wheel studs with quality anti-seize paste, torque should closely follow the vehicle OEM manufacturer specification (typically 110–135 Nm for M12 threads, and 140–160 Nm for M14 threads). We strongly advise using calibrated manual torque wrenches rather than pneumatic impact guns for the final seating to maintain precise clamping tension without over-stretching the fastener.

Every OEM/ODM batch from Velnora is accompanied by complete quality assurance documentation: Raw Material Mill Test Certificates (EN 10204 3.1) confirming chemical composition (Al, V, Fe, C, N, H, O content) and mechanical tensile data; Full Dimensional Inspection Reports using coordinate measuring machines (Zeiss CMM) and optical thread profile projectors; and Certificate of Conformance (CoC). Non-Destructive Testing (NDT) reports, including ultrasonic flaw detection and dye penetrant testing, can also be provided upon client specification.

For custom OEM/ODM titanium wheel studs requiring new CNC tooling or specific thread rolling dies, our standard MOQ is typically 100 to 300 pieces per dimensional specification. Prototype sample runs (20–50 pieces) can be scheduled for engineering fitment tests in approximately 10 to 15 business days. Mass production runs generally dispatch within 20 to 30 days after drawing sign-off, supported by express air freight (DHL, FedEx, UPS) or consolidated sea freight.
