China Titanium UFO Head Torx Self Tapping Bolts Supplier - Durable Motorcycle Fairing Fasteners from Factory
Key Features
Integrated Wide Flange for Washer-Free Clamping
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.
Low-Profile Rounded UFO Head Design
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.
Integrated Wide Sealing Flange
The wide flange increases contact with crush washers. It spreads clamping force evenly under high brake pressure, helping prevent leaks during repeated use.
Deep Engagement Precision Torx Drive
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.
Aggressive Self-Tapping Thread for Strong Grip
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.
Installation & Maintenance Guidance
Compatible Materials. Suitable for moderately pliable substrates such as aluminum, magnesium, plastics, and carbon fiber composites. Not recommended for steel, cast iron, or other very hard materials.
Pre-Drilling Recommendation. For titanium UFO head bolts on high density plastics or carbon fiber panels, pre-drill pilot holes (M5: 3.8–4.2mm) to ensure proper threading.
Safety Notice. Self-tapping threads mean these screws must not be used in pre-threaded critical components like engines, brakes, or drivetrain assemblies.
Corrosion & Oxidation Care. Although titanium never rusts, to maintain the vibrancy of anodized finishes, avoid using strong acids or alkaline cleaners during washing.

Application Scenarios
1. Motorcycle Customization
● Body Panels & Fairings
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)
● Detail Components & Mounts
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).
2. Lightweight & Specialty Parts
● Carbon Fiber Panels
Titanium UFO head bolts are suitable for carbon fiber sheets, custom trim panels, and aerodynamic covers. (Recommended sizes M5 / M6)
● High-End Devices & Outdoor Equipment
These Bolts can also be applied in drone housings, action camera mounts, and marine plastic panels. (Recommended M4–M5 sizes)
Frequently Asked Questions
Q1: Do these titanium UFO head bolts require separate washers?
No, they do not. Each titanium UFO head bolt features an integrated wide flange that functions as a built-in washer. This distributes clamping force and prevents cracking in carbon fiber or plastic.
Q2: What materials are compatible with these bolts?
They are suitable for moderately pliable substrates like aluminum, magnesium, plastics, and carbon fiber composites. They are not recommended for hard materials such as steel or cast iron.
Q3: Can I use these self-tapping bolts for engine or brake assemblies?
No. Because they feature self-tapping threads, they must not be used in pre-threaded critical components such as engines, brakes, or drivetrain assemblies.
Q4: Is pre-drilling required before installation?
Yes, pre-drilling pilot holes (e.g., 3.8–4.2mm for M5 bolts) is highly recommended when installing them on high-density plastics or carbon fiber panels to ensure proper threading.
Q5: How should I clean these bolts to protect their finish?
Although titanium is rust-proof, you should avoid using strong acids or alkaline cleaners during washing to maintain the vibrancy of anodized color finishes.
Q6: What are the benefits of the Torx drive on these bolts?
The Torx drive provides a larger contact area compared to standard hex sockets. This stabilizes torque transfer, reduces the risk of tool cam-out, and keeps the drive precise over repeated use.
