Gr5 Titanium Flanged Hex Head Bolts for Performance Vehicles & Industrial Use
Key Features
● Integrated Flange for Consistent Clamping
Titanium flanged hex head bolts feature a built-in washer flange that evenly distributes clamping force and prevents component damage. They are particularly suitable for engine mounting brackets, brake calipers, and structural joints in motorcycles and automotive assemblies.
● Stable Preload & Precision Torque
CNC-machined threads (±0.05 mm tolerance) and cold-rolled processing ensure smooth engagement and repeatable clamping. The titanium flanged hex head bolts maintain stable preload in high-vibration conditions such as motorcycle frames or robotic actuators.
● Protective Load Distribution
The flange spreads clamping force across soft surfaces like aluminum or magnesium, reducing deformation and enhancing joint longevity in engine covers, intake manifolds, and lightweight chassis components.
● Functional Multi-Color Titanium Finishes
We offer natural, burnt blue, gold, purple, and rainbow anodized finishes. Beyond aesthetics, anodizing improves surface hardness and reduces friction, extending bolt life in demanding environments.
● Lightweight Strength for Performance Applications
Crafted from aerospace-grade Ti-6Al-4V, these bolts offer exceptional strength-to-weight ratio, reducing unsustainable mass or structural load. This is critical for motorcycles, e-bikes, and high-performance automotive components.
Installation & Maintenance Guidance
Uniform Flange Pressure – Tighten in a cross-pattern to avoid flange deformation.
Thread Protection – Clean flange underside and mating threads; apply titanium-compatible anti-seize on aluminum surfaces to prevent galling.
Torque Accuracy – Follow calibrated torque specs to maintain secure clamping without over-stressing components.

Application Scenarios
● Motorcycle Assemblies
Titanium flanged hex head bolts are used in engine brackets (M8–M10), frame joints (M6–M10), and brake calipers (M8). The integrated flange ensures uniform clamping and prevents aluminum or magnesium surface damage. Ideal for racing motorcycles and high-performance street bikes requiring repeated assembly.
● Automotive Performance
These bolts are applied in intake manifolds (M6–M8), transmission covers (M8–M10), and lightweight chassis mounts (M10–M12). The flange design and Ti-6Al-4V strength reduce localized stress and maintain reliable clamping under thermal cycling and vibration.
● High-End Bicycles & E-Bikes
Commonly used in suspension linkages, e-bike motor mounts, and adapter blocks (M6–M8) where enhanced clamping strength and corrosion resistance are required.
● Robotics & Industrial Machinery
Titanium flanged hex head bolts secure actuator housings, modular frames, and robotic joints (M6–M12). The flange ensures stability under high-frequency vibration for repeatable long-term assembly reliability.
● Industrial Equipment & Maintenance
They are ideal for pumps, compressors, and enclosures. The universal flange design allows OEMs and distributors to reduce part inventory and simplify assembly management.
Frequently Asked Questions
Q1. What are the advantages of using Grade 5 titanium flange hex head bolts instead of standard hex bolts?
A: Grade 5 titanium flange hex head bolts have an integrated flange under the head. The flange increases the contact area with the mounting surface. This helps spread the clamping force more evenly. They are suitable for applications that require lightweight fasteners with stable fastening performance.
Q2. Can these titanium flange hex head bolts be customized for specific applications?
A: Yes. Custom titanium flange hex head bolts are available for different application requirements. Customers can request specific thread sizes, dimensions, surface finishes or other design details. This allows the fasteners to match different installation conditions and project requirements.
Q3. What should be considered when installing titanium flange hex head bolts?
A: During installation, the flange surface should contact the mounting part evenly. Proper thread preparation and accurate torque control are important for reliable fastening. Following suitable installation procedures helps achieve consistent clamping performance and reduces potential installation problems.
