Grade 5 Titanium Hex Head Bolts - High Strength & Corrosion-Resistant | China Suppliers & Factory for Industrial Use
Key Features
High Torque Efficiency & Precise Assembly
Titanium hex head bolts hex geometry maximizes torque transfer with minimal deformation. CNC-machined Grade 5 titanium enables lightweight yet robust assembly of motorcycle swingarms, automotive engine mounts, and industrial joints. This reliable torque characteristic supports repeated assembly and cyclic maintenance.
Superior Load & Thermal Resistance
These titanium hex head bolts maintain structural integrity under heavy loads and −100°C to +450°C. Suitable for high-vibration engine mounts, robotic arms, and precision machinery, providing long-term reliability and fatigue resistance.
Thread Versatility & Maintenance Efficiency
Available in metric coarse and fine threads (M3–M16) with ±0.05 mm tolerance and Cold-rolled threads reduce galling. These bolts support repeated disassembly without compromising torque retention, suitable for automotive, motorcycle, and industrial maintenance.
Custom Finishes & Branding Options
Polished, anodized, or PVD-coated finishes are available, along with optional color customization, logo engraving, and OEM packaging. Perfect for projects requiring specialized finishes or brand identification.
Lightweight & Fatigue-Resistant
Grade 5 titanium offers low density (4.43 g/cm³) while maintaining ≥900 MPa tensile strength. Using titanium hex head bolts reduces unsprung weight, improving handling stability and overall performance in motorcycles, bicycles, and e-bikes.
Installation & Maintenance Guidance
✔
Apply high-quality anti-seize compound for titanium-to-titanium or titanium-to-aluminum connections to prevent galling.
✔
Follow recommended torque specifications for each titanium hex head bolt size.
✔
Hex head allows easy access in tight spaces with standard hand or power tools.

Frequently Asked Questions
What are the primary benefits of using Grade 5 Titanium hex head bolts?
Grade 5 Titanium (Ti-6Al-4V) provides a high strength-to-weight ratio (being 55% lighter than steel), excellent fatigue resistance, outstanding thermal stability (-100°C to +450°C), and exceptional corrosion resistance in harsh environments.
Why is anti-seize compound recommended during installation?
Anti-seize compound is highly recommended for titanium-to-titanium or titanium-to-aluminum connections to prevent thread galling (cold welding) and to ensure accurate torque application.
Are custom thread sizes and lengths available?
Yes, we offer standard metric threads from M3 to M16 in lengths ranging from 8mm to 120mm. Custom dimensions, thread pitches, and OEM specifications can also be manufactured upon request.
What surface finishes can be applied to these bolts?
We offer multiple surface treatments including polishing, anodizing, and PVD coating. This allows for various color customizations (Silver, Gold, Blue, Purple, Black) and improved surface durability.
Can these titanium bolts be used in high-vibration applications?
Absolutely. Their high tensile strength (≥ 900 MPa) and cold-rolled threads provide superior resistance to fatigue and shear, making them ideal for high-vibration environments like motorcycle engines and robotic machinery.
