Grade 5 Titanium Hex Head Bolts for Motorcycle, Automotive and 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
Q1. Why choose Grade 5 titanium hex head bolts instead of socket head cap bolts?
A: Grade 5 titanium hex head bolts use a traditional external wrenching design. They are suitable for applications where easy installation and tool access are important. Socket head cap bolts are often preferred for compact spaces, while hex head bolts are commonly used when a standard wrench installation is required.
Q2. Can Grade 5 titanium hex head bolts be customized for specific motorcycle or industrial applications?
A: Yes. Grade 5 titanium hex head bolts can be customized for different application needs. Custom options may include thread size, length, surface finish and other specifications. This allows customers to select suitable fasteners for motorcycle builds, performance projects and industrial equipment.
Q3. How should I select the correct titanium hex head bolt for my application?
A: The correct titanium hex head bolt should be selected according to thread specification, bolt length, installation space and load requirements. Customers should also consider the working environment and connection purpose to ensure the fastener meets the application needs.
