China Factory Suppliers Race Spec Titanium Hex Flange Bolt for Motorcycle Racing – Lightweight & Strong Grade 5 Titanium
Key Features
Race Spec Weight Reduction
The race spec titanium hex flange bolt features a concave dome top with six drilled sides, removing non-structural mass while keeping all critical Grade 5 titanium load paths intact. This design reduces unsprung weight and enhances rotational response, and perfect for high-performance racing modifications.
Pre-Drilled for Safety Wire
Six precision 1.5–2.0 mm holes on the flange head allow stainless-steel safety wire installation. This ensures secure locking under extreme vibration or heat cycles, meeting motorsport standards and providing reliable torque stability.
Premium Aesthetic & Surface Treatment
Available in Burnt Blue, Gold, PVD Black, Rainbow, and Polished Silver. Controlled anodizing and PVD coatings ensure consistent color, corrosion resistance, and a refined finish, making the race spec titanium hex flange bolt both visually striking and exceptionally durable.
Integrated Flange Design
The one-piece flange increases the seating area, evenly distributing clamp force without extra washers. It protects sensitive aluminum and carbon fiber components from marks or deformation while keeping fastening consistent across repeated torque cycles.
High-Precision Rolled Threads
Precision-rolled threads preserve the continuity of the metal grain flow, significantly improving fatigue strength and wear resistance. Even after repeated assembly, the race spec titanium hex flange bolt remains smooth and resistant to galling.
Installation & Maintenance Guidance
Apply a dedicated anti-seize lubricant to the threads. This prevents cold welding when the race spec titanium hex flange bolt is installed in aluminum or steel components.
Follow the recommended torque values. The hollow and drilled head design requires careful torque control—avoid over-tightening to prevent any structural damage.
Use precise hex or 12-point sockets. This protects the coated surfaces and sharp edges of the race-spec head from damage during installation.

Application Scenarios
Motorcycle Racing Components
It is most commonly used in brake calipers, rotors, sprockets, and engine covers where lightweight design and wire-lock capability are essential. Recommended M6–M10, 18–40 mm. The race spec titanium hex flange bolt reduces rotating mass and secures fasteners under track vibration.
Automotive Performance
The titanium racing bolts are ideal for engine-bay upgrades, chassis trim, and non-structural lightweighting. M6 or M8 bolts secure covers, brackets, and trim while maintaining thermal stability and a clean appearance. They can provide reliable fastening and refined visuals.
Professional Bicycle Tuning
Perfect for cranks, stems, or lightweight drivetrain components on road, time trial, or downhill bikes. M6 bolts reduce mass while keeping torque control precise. These bolts help preserve structural integrity in sensitive racing setups.
Marine & Outdoor Precision Equipment
Designed for saltwater or outdoor use, M6–M8 race spec titanium hex flange bolts secure brackets, housings, and modular parts. Titanium’s corrosion resistance is enhanced by anodized or PVD finishes, providing durable and reliable fastening over time.
Frequently Asked Questions
What material is used for these race spec bolts?
They are manufactured from high-quality Grade 5 Titanium (Ti-6Al-4V), offering a density of 4.43 g/cm³ and a tensile strength of ≥ 900 MPa for excellent performance and durability.
Why are the flange heads pre-drilled?
The head features six precision 1.5–2.0 mm holes that allow the installation of stainless-steel safety wire. This ensures the bolts remain securely locked and maintain torque stability under extreme vibration and heat cycles.
What is the advantage of the integrated flange design?
The one-piece flange design increases the seating area to distribute clamping force evenly. This eliminates the need for separate washers and protects sensitive materials like carbon fiber and aluminum from indentation or deformation.
Are these titanium bolts resistant to corrosion?
Yes, Grade 5 Titanium features outstanding natural corrosion resistance. This is further enhanced by our premium surface finishes, including anodized and PVD coatings, making them ideal for marine and outdoor environments.
What measures should be taken during installation?
It is highly recommended to apply a dedicated anti-seize lubricant to the threads to prevent galling or cold welding. Additionally, you should use precise hex or 12-point sockets and follow recommended torque limits to avoid damage to the hollow, lightweight head.
Can I customize the thread pitch, length, or finish?
Yes, OEM customization is fully supported. We offer options for custom thread types, lengths, head styles, and finishes including Burnt Blue, Gold, PVD Black, Rainbow, and Polished Silver.
