China Titanium UFO Head Torx Self Tapping Bolts Supplier - Factory Direct, M4/M5/M6 for Motorcycle Fairings
Key Features
Every titanium UFO head bolt features a one-piece wide flange that works like a built-in washer. It spreads clamping force across a larger area and reduces stress on plastic or carbon fiber. This helps prevent cracking over time and removes the need for extra washers.
The UFO head has a slim shape with smooth rounded edges. It sits flush after installation and leaves no sharp protrusions. This creates a cleaner look while reducing snagging risks or accidental scratches during daily use.
The wide flange increases contact with crush washers. It spreads clamping force evenly under high brake pressure, helping prevent leaks during repeated use.
The Torx drive provides more contact than a standard hex socket. Torque transfer feels more stable and controlled during installation. It reduces cam-out risk and stays precise even after repeated installation and removal.
Sharp, deep-cut threads allow titanium UFO head bolts to bite firmly into plastic and composite materials. The connection stays secure under vibration and is less likely to loosen over time.

Application Scenarios
Titanium UFO head bolts are ideal for securing motorcycle fairings, side covers, dashboards, fenders, and windshields. They ensure stable fastening without cracking plastic panels. (Recommended M5 × 12–20mm)
They work well for license plate brackets, light covers, and small non-structural plastic mounts. The self-tapping threads hold parts firmly, even on vibration-prone areas (recommended M4 / M5).
Titanium UFO head bolts are suitable for carbon fiber sheets, custom trim panels, and aerodynamic covers. (Recommended sizes M5 / M6)
These Bolts can also be applied in drone housings, action camera mounts, and marine plastic panels. (Recommended M4–M5 sizes)
Frequently Asked Questions (FAQ)
What are the main benefits of the integrated wide flange on these bolts?
The integrated wide flange functions as a built-in washer. It distributes the clamping force over a larger surface area, which helps minimize stress on delicate materials like plastic or carbon fiber, preventing cracking and eliminating the need for separate washers.
Which materials are compatible with Titanium UFO head bolts?
They are highly suitable for moderately pliable substrates, including aluminum, magnesium, plastics, and carbon fiber composites. However, they are not recommended for extremely hard materials such as steel or cast iron.
Can I use these self-tapping bolts for safety-critical components?
No. Because they feature self-tapping threads, these screws must never be used in pre-threaded critical components such as engine assemblies, brakes, or drivetrain systems.
Do I need to pre-drill holes before installing these self-tapping bolts?
Yes, when installing titanium UFO head bolts on high-density plastics or carbon fiber panels, it is recommended to pre-drill pilot holes (for example, 3.8–4.2mm for M5 bolts) to guarantee clean and proper threading.
How should I clean and maintain anodized titanium bolts?
While titanium itself is completely rust-proof, the anodized color finishes can degrade. To preserve the vibrancy of the color, avoid using strong acids or highly alkaline cleaning agents during washing.
What mechanical specifications do these Grade 5 Titanium bolts offer?
These bolts are made of Grade 5 Titanium (Ti-6Al-4V) with a density of 4.43 g/cm³. They deliver a high tensile strength of ≥ 900 MPa, a yield strength of ≥ 830 MPa, and a hardness rating of 30–36 HRC, offering excellent corrosion resistance.
