Grade 5 Titanium Hex Head Bolts for Motorcycle, Automotive & Industrial Use - China Suppliers & Factory
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
