Race Spec Titanium Hex Flange Bolt for Motorcycle Racing - China Suppliers & Factory Direct Quality
Key Features
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.
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.
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.
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.
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.
