Dual-Drive Titanium Hex Flange Bolt for Motorcycles - China Suppliers & Factory Grade 5 Titanium Components
Key Features
Versatile Dual-Drive Interface
The dual-drive titanium hex flange bolt combines an external hex flange with an internal hex recess, giving riders and mechanics flexible tool options. This dual layout improves practicality during regular maintenance and roadside adjustments.
Optimized for Tight-Access Installation
Its top recessed hex allows vertical engagement where side clearance is restricted. This dual-drive titanium hex flange bolt design makes it far easier to work with in crowded engine areas where standard titanium fasteners struggle to fit a socket.
Balanced Design for Non-Extreme Load Points
Compared with concave racing bolts, this head offers the same sporty appearance but allows much easier installation. It slightly sacrifices torsional limit, making it ideal for non-extreme load parts like covers or brackets while keeping the build’s visual style consistent.
Race Ready Safety Wire Drillings
Six precisely positioned holes along the flange provide secure routing for stainless safety wire. This mechanical locking method prevents loosening under high-frequency vibrations and adds a distinctly technical, race-grade look to exposed fasteners.
Rolled Threads for Long-Term Durability
Made from Ti-6Al-4V aerospace-grade titanium with precision-rolled threads, these dual-drive titanium hex flange bolts resist fatigue and galling, ensuring smooth, durable fastening even under frequent assembly and disassembly.
Installation & Maintenance Guidance
Select Proper Tools. Use the external hex for any higher torque tightening. The internal hex works best in tight access areas or for lighter adjustments, helping preserve the integrity of both drive interfaces.
Avoid Over-Torquing Internal Hex. When using the internal hex, follow the recommended lower torque range. Its thinner wall profile naturally concentrates stress at the corners, so controlled torque prevents long-term socket wear.
Standard Anti-Galling Maintenance. Always apply anti-seize before installation. It prevents thread galling on titanium fasteners and ensures smooth removal during future servicing.

Application Scenarios
1. Motorcycle Performance & Maintenance
● Engine & Case Covers
Well-suited for side covers such as clutch and ignition covers. The dual-drive titanium hex flange bolt helps speed up oil changes and routine servicing, especially in tight engine areas.
● Bodywork & Fairing Brackets
A reliable choice for fairings and fender brackets exposed to constant vibration. The six-side drilling pattern supports motorsport lock-wiring, keeping hardware secure under heavy-duty riding.
● Cockpit & Controls
Ideal for tight spaces around the handlebars where sockets cannot reach. They are often used for brake master-cylinder mounts and switch housings, offering a cleaner fit and easier upgrades.
2. Other High-End Applications
● Versatile Performance Tuning
These dual-drive titanium hex flange bolts are also suitable for premium bicycle cranksets, automotive engine-bay dress-up parts, and marine or robotic assemblies that demand strong corrosion resistance.
Frequently Asked Questions
What is the advantage of a dual-drive titanium hex flange bolt?
It combines an external hex flange with an internal hex recess, offering flexible tool options for easy maintenance, especially in tight spaces where side clearance is restricted.
Can these titanium bolts be used for extreme load applications?
These bolts feature a balanced design optimized for non-extreme load points like covers or brackets. While they offer a sporty look and easier installation, they have a slightly lower torsional limit compared to concave racing bolts.
What are the safety wire drillings used for?
The flange is designed with six precisely positioned holes for routing stainless safety wire. This mechanical locking method prevents the bolt from loosening under high-frequency vibrations, which is ideal for race-ready setups.
Why are rolled threads better for titanium bolts?
Precision-rolled threads provide higher resistance to fatigue and galling. This ensures smoother fastening and long-term durability, even with frequent assembly and disassembly.
Should I use anti-seize during installation?
Yes, applying anti-seize before installation is highly recommended. It prevents thread galling on titanium fasteners and ensures smooth removal during future servicing.
What sizing and customization finishes are available?
We support OEM customization with diameter ranges from M5 to M10, lengths from 10 to 70 mm, and finish options including Burnt Blue, Natural, Silver, Gold, Black, and Rainbow.
