Grade 5 Titanium Flower Head Flange Bolts with Torx Drive - China Suppliers and Factory Direct on Motorcycle, Bicycle, Automotive
Key Features
Precision Dual-Tier Scalloped CNC Design
Machined using a high-precision CNC machining center. The six-petal, dual-layer concave profile increases light reflection and visual depth. These Titanium flower head bolts also function as a visible design element in high-end assemblies.
Integrated Wide Flange Head
The head and flange are formed as a single piece. The wide, flat base distributes clamping force more evenly. It removes the need for washers and helps reduce noise caused by loosened hardware.
Grade 5 Titanium Construction (Ti-6Al-4V)
Manufactured from TC4 titanium with tensile strength ≥ 895 MPa. It offers a clear weight advantage compared to steel fasteners. At the same time, it maintains stable mechanical performance in demanding conditions.
High-Tolerance Torx Drive
The Torx drive provides a larger contact area than standard hex sockets. This reduces the risk of rounding during repeated installation and removal. In practice, Titanium flower head bolts maintain better head condition over time across different sizes.
Stable PVD & Anodized Color Finish
Surface colors are applied through controlled PVD or anodizing processes. The coating shows consistent tone and good adhesion. It remains stable under long-term exposure to sunlight and heat.
Installation & Maintenance Guidance
1
Correct Tooling (Torx Fitment): Ensure the Torx driver (T25 / T30 / T45) matches the bolt size and is in good condition. Proper engagement helps protect the precision machined scalloped edges.
2
Avoid Harsh Chemical Cleaning: Surface finishes are applied by anodizing or PVD processes. Avoid strong acidic or alkaline cleaners. Use neutral solutions to maintain color consistency.
3
Thread Lubrication: Apply anti-seize to threads before installation. This helps prevent galling and ensures smooth removal, especially during repeated assembly.

Application Scenarios
Motorcycle Applications
Fairings, Body Panels & Engine Covers
Fairings, side panels, and engine covers typically require M5–M6 fasteners in visible areas. Titanium flower head bolts improve visual consistency while keeping panel removal simple during routine service.
Brake Disc & Decorative Hardware
Brake disc bolts and exposed engine hardware benefit from consistent head styling. These fasteners help maintain a unified appearance without affecting access for maintenance.
Other Applications
Bicycle Stem, Brake Rotor & Bottle Cage Mounts
On high-end bicycles, M5 fasteners are used across stems, rotors, and accessories. Titanium flower head bolts provide refined hardware detail while keeping installation straightforward.
Automotive Engine Bay Covers & Visible Trim Points
Engine covers, brackets, and trim points are often secured with M6–M8 fasteners in exposed areas. These fasteners help achieve a more consistent hardware appearance in detail-focused engine bays.
Frequently Asked Questions
What material are these flower head bolts made of?
They are manufactured from Grade 5 Titanium (Ti-6Al-4V / TC4) which features a tensile strength of ≥ 895 MPa and provides a substantial weight advantage over traditional steel fasteners.
What are the benefits of the integrated wide flange head design?
The integrated head and flange design distributes clamping force more evenly across a wider, flat base. This eliminates the need for separate washers and helps prevent noise caused by loosened hardware.
Why is a Torx drive used instead of a standard hex socket?
The Torx drive increases the contact area between the tool and the bolt head, reducing the risk of rounding the drive during repeated installation and removal cycles.
How should I clean and maintain the colored finishes?
Because the finishes are applied via PVD or anodizing, you should avoid strong acidic or alkaline chemical cleaners. Instead, use neutral cleaning solutions to maintain the color consistency.
Is thread lubrication required during installation?
Yes, applying anti-seize lubricant to the threads before installation is highly recommended to prevent galling and ensure smooth removal during future maintenance.
Can these bolts be customized to specific dimensions or colors?
Yes, OEM customization is supported. You can customize the size, length, finish type, color, and even request custom logo engraving.
