Dual-Drive Titanium Hex Flange Bolt - High-Performance Motorcycle Parts from China Suppliers & Factory
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
Q
What are the benefits of a dual-drive titanium hex flange bolt design?
The dual-drive design combines an external hex flange with an internal hex recess. This provides flexible tool options, making it easier to install and maintain components in tight-access areas where side clearance for standard sockets is restricted.
Q
Why are there holes drilled in the flange of the bolt?
The flange has six precisely positioned safety wire holes. This allows mechanics to run safety wires through the bolt head, preventing it from loosening under high-frequency vibrations, which is a standard safety requirement in motorsports.
Q
Which tools should I use to install these bolts?
You should use the external hex for higher torque tightening to prevent wear. The internal hex recess is ideal for tight-access areas or lighter, low-torque adjustments to preserve both drive interfaces.
Q
What grade of titanium is used, and what are its properties?
These bolts are made from Grade 5 Titanium (Ti-6Al-4V). This aerospace-grade material features a density of 4.43 g/cm³, a tensile strength of ≥ 900 MPa, yield strength of ≥ 830 MPa, and excellent corrosion resistance.
Q
How do I prevent thread galling during installation?
To prevent thread galling on titanium fasteners, you should always apply an anti-seize compound before installation. This ensures smooth torque delivery and easy removal during future maintenance.
Q
Are custom sizes, finishes, and logo engraving supported?
Yes, OEM customization is supported. You can customize the thread type, head style, length, and choose from finishes like Burnt Blue, Natural, Silver, Gold, Black, and Rainbow, along with custom logo engraving.
