Featured Titanium Screw Kits & Precision Fasteners
Manufactured from certified aerospace-grade raw stock to ASTM, DIN, and GB standards with tight CNC tolerances up to 0.005 mm.
Engineering Dynamics of High-Performance Titanium Fastening
Bridging the gap between raw metallurgy and critical structural performance across extreme operational environments.
High Strength-to-Weight Ratio
Grade 5 (Ti-6Al-4V) delivers a minimum tensile strength of 895 MPa at roughly 4.43 g/cm³—providing steel-level mechanical load capacity at approximately 56% the weight of alloy steel, critical for unsprung weight reduction in motorsport and high-stress marine assemblies.
Rolled Threads vs. Cut Threads
Unlike standard thread cutting that severs grain boundaries, our high-stress kits use precision cold-rolling dies to form threads. This preserves continuous grain flow, work-hardens the thread root, and yields up to a 30% increase in fatigue life under cyclic dynamic vibration.
Advanced Anti-Galling & PVD
Titanium naturally forms a self-healing oxide film (TiO2) that resists chlorides and road salts, yet exhibits galling under sliding torque. We mitigate this through micro-finished thread geometry, specialized PVD nitriding, and hard-anodized protective layers engineered for repeatable friction coefficients.
Fastener Grade Selection Matrix
Compare mechanical limits, working conditions, and engineering applications across major titanium formulations.
| Material Grade | Composition | Tensile Strength (MPa) | Yield Strength (MPa) | Key Application Scenarios |
|---|---|---|---|---|
| Grade 2 (CP Titanium) | Commercially Pure Ti | ≥ 345 | ≥ 275 | Marine exhaust hardware, chemical flow valves, high-chloride environments. |
| Grade 5 (Ti-6Al-4V) | Ti-6Al-4V (Alpha-Beta) | ≥ 895 | ≥ 828 | Engine head studs, brake rotor hardware, suspension turnbuckles, wheel nuts. |
| Grade 23 (ELI Ti-6Al-4V) | Ti-6Al-4V Extra Low Interstitial | ≥ 860 | ≥ 795 | Medical orthopedics, surgical fixations, cryogenic structural hardware. |
| Grade 9 (Ti-3Al-2.5V) | Ti-3Al-2.5V Half-Alloy | ≥ 620 | ≥ 483 | Hydraulic pressure lines, structural bicycle tubing, lightweight linkages. |
Titanium Hardware Procurement & Industry Trends
Critical shifts shaping global supply chains, engineering requirements, and manufacturing technology through 2026 and beyond.
Electrification & Unsprung Mass Optimization
With electric vehicle (EV) architectures prioritizing maximum battery range, automotive tier-1 manufacturers are replacing traditional alloy steel hardware with Ti-6Al-4V screw kits. Eliminating mass at the wheel hubs, suspension linkages, and drive unit brackets reduces rotational inertia while directly offsetting battery pack weight.
Turnkey OEM Kitting & Custom Serialization
Global procurement teams are moving away from bulk hardware bins toward bespoke, pre-bagged screw kits labeled with laser-etched part numbers, torque specifications, and QR codes. Turnkey kits accelerate vehicle and engine assembly workflows, preventing cross-threading errors and ensuring strict assembly-line accountability.
Total Sponge-to-Bolt Traceability
Stricter regulatory compliance across automotive safety standards and industrial guidelines demands end-to-end traceability. Buyers now require verifiable metallurgical trail maps—from vacuum arc remelting (VAR) titanium sponge certification to calibrated optical dimensional reports for every manufacturing run.
Why Partner With Vunza in China's Titanium Valley
Direct integration into the world's most concentrated titanium industrial cluster provides unmatched quality assurance and cost resilience.
Baoji Supply Chain Integration
Located in the Gaoya Village Industrial Zone adjacent to Baoti Group, our plant taps directly into premier smelting, forging, and ingot supply channels. This cluster density ensures guaranteed access to virgin aerospace titanium stock, minimizing raw-material price volatility and eliminating third-party supply chain delays.
High-Precision CNC Fleet
Our workshop houses 34 multi-axis (3, 4, and 5-axis) CNC turning-milling centers capable of maintaining linear tolerances within 0.005 mm. With over 50% of our production team possessing more than 13 years of titanium machining expertise, we execute complex head forms, internal hex/Torx designs, and weight-relief gun-drilling in single setups.
Closed-Loop Quality Control
From spectrometry testing on incoming raw billet stock to optical profile projectors, thread-pitch micrometer verifications, and go/no-go ring gauges on the plant floor, each production lot undergoes verified first-article, in-process, and outgoing inspections accompanied by Mill Test Certificates (MTCs).
