Race Spec Titanium Hex Flange Bolts for Motorcycle Racing - High Strength, Lightweight, China Suppliers & Factory
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.

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.
A: The integrated flange provides a wider contact surface compared with a standard hex bolt. It can help simplify installation by combining the bolt head and washer function in one design.
A: The drilled holes allow the bolt to be secured with safety wire when additional locking protection is required. This design is often considered for high-vibration applications such as racing environments.
A: The flange diameter, bolt length, and installation clearance should be confirmed before use. Proper sizing helps ensure the bolt fits the intended motorcycle component correctly.
A: The combination of titanium material, flange head design, and optional PVD finishes makes them suitable for performance-oriented motorcycle projects. They are often selected where lightweight hardware and appearance are both considered.
A: They are 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.
A: They are manufactured from Grade 5 Titanium (Ti-6Al-4V) with a density of 4.43 g/cm³, featuring a high tensile strength of ≥ 900 MPa and yield strength of ≥ 830 MPa.
