Grade 5 Titanium Hex Head Bolts for Motorcycle & Automotive - China Suppliers Factory with Custom Sizes
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 (FAQ)
What are the main benefits of Grade 5 Titanium Hex Head Bolts over steel bolts?
Grade 5 Titanium (Ti-6Al-4V) bolts offer an exceptional strength-to-weight ratio. They are approximately 55% lighter than steel while maintaining a high tensile strength of ≥ 900 MPa. They also provide outstanding corrosion resistance in salt, moisture, and extreme temperatures.
Why is anti-seize compound recommended for installation?
Titanium has a natural tendency to gall (cold weld) when friction is applied against other metals, especially titanium or aluminum. Applying a high-quality anti-seize compound prevents thread galling and allows for precise torque application and easy disassembly.
What temperature range can these titanium bolts withstand?
These bolts maintain their structural integrity and mechanical properties under extreme thermal conditions ranging from −100°C up to +450°C, making them ideal for high-heat automotive and industrial environments.
Are custom thread sizes and finishes available?
Yes. We supply metric coarse and fine threads ranging from M3 to M16 with a tolerance of ±0.05 mm. Available surface finishes include polished, anodized, and PVD coatings in colors like silver, gold, blue, purple, and black.
Can these hex head bolts be reused after disassembly?
Yes. Thanks to cold-rolled threads and superior fatigue resistance, these titanium hex head bolts support repeated assembly and cyclic maintenance disassembly without compromising torque retention or thread structure.
