Race Spec Titanium Hex Flange Bolt for Motorcycle Racing
Summary The race spec titanium hex flange bolt uses a hollowed dome top with six drilled sides for extreme weight reduction while retaining critical Grade 5 titanium strength. Pre-drilled for safety wire, it stays secure under high vibration. Perfect for racing bikes and performance builds needing reliable, precise fastening.
Quick Specs Material: Grade 5 Titanium (Ti-6Al-4V) Head Type: Truss Head Size Range: M4–M6 Length Range: 8–30 mm Drive Type: Torx Finish Options: Silver / Gold / Blue / Black / Rainbow Titanium Application: Motorcycle & Bicycle Panels MOQ: 100 pcs
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
Q1. Why choose a flange head design for motorcycle applications?
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.
Q2. What is the purpose of the drilled holes on the bolt head?
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.
Q3. What should be checked before installing these flange bolts on a motorcycle?
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.
Q4. Are these titanium flange bolts suitable for custom motorcycle builds?
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.
