High-Strength Grade 5 Titanium Hex Head Bolts Suppliers in China - Factory for Motorcycle, Automotive & 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.

Frequently Asked Questions
What grade of titanium is used for these hex head bolts?
Our titanium hex head bolts are manufactured using high-strength Grade 5 Titanium (Ti-6Al-4V), offering a minimum tensile strength of 900 MPa and excellent fatigue resistance.
Why is it recommended to use anti-seize compound during installation?
Applying a high-quality anti-seize compound prevents galling (cold welding) of threads, which is a common occurrence when installing titanium fasteners into titanium or aluminum components.
Are custom finishes and colors available for these bolts?
Yes. We support custom surface finishes including high polishing, anodizing, and PVD coating. Available colors include silver, gold, blue, purple, and black.
What thread types and standards do these bolts follow?
We offer metric coarse and fine threads ranging from M3 to M16. The partial thread bolts conform to the ISO 4014 standard, while full thread bolts comply with the DIN 933 standard.
How much weight can I save by switching to titanium hex head bolts?
Grade 5 titanium has a density of 4.43 g/cm³, which makes it approximately 55% lighter than traditional steel bolts while offering equivalent or superior mechanical strength.
