Grade 5 Titanium Hex Flange Banjo Bolt - Pre-Drilled Safety Wire Holes | China Factory Suppliers for Motorcycle Systems
Key Features
Each titanium banjo bolt head is pre-drilled with six evenly spaced safety wire holes. When secured with safety wire, it prevents loosening under vibration and meets track-day and professional racing inspection standards.
The internal oil passage is polished to reduce fluid resistance. This delivers smoother, more linear brake lever feel compared with OEM steel bolts.
The wide flange increases contact with crush washers. It spreads clamping force evenly under high brake pressure, helping prevent leaks during repeated use.
Manufactured from Ti-6Al-4V, the titanium banjo bolt weighs about 45% less than steel bolts. Reduced unsprung weight improves suspension response and steering agility for performance upgrades.
Optimized for DOT4 and DOT5.1 fluids, this titanium banjo bolt resists rust, oxidation, and staining. It keeps brake hardware clean and easy to service.

Application Scenarios
The titanium banjo bolt is mainly used on M10 brake line fittings linking calipers and master cylinders. Reduced weight at the fork supports quicker suspension response, and the safety wire holes meet track inspection rules.
Installed on M8 or M10 hydraulic clutch connections. It ensures secure clamping and stable sealing through repeated heat cycles for consistent clutch feel.
Compatible with Brembo calipers and Japanese brake systems like Nissin, Tokico, and Magura. M10 is commonly used on front brakes, while M8 fits compact hydraulic setups.
Frequently Asked Questions (FAQ)
What material is the titanium banjo bolt made of?
It is manufactured from Grade 5 Titanium (Ti-6Al-4V), offering a density of 4.43 g/cm³, tensile strength ≥ 900 MPa, and yield strength ≥ 830 MPa for high strength and durability.
How much weight can I save by using this titanium banjo bolt?
This titanium banjo bolt is approximately 45% lighter than standard steel bolts. Reducing this unsprung weight helps improve motorcycle suspension response and steering agility.
Why does the banjo bolt head have six pre-drilled holes?
The six pre-drilled safety wire holes allow you to secure the bolt with safety wire. This effectively prevents the bolt from loosening under high vibration and meets track-day and professional racing inspection standards.
Is this titanium banjo bolt compatible with Brembo brake systems?
Yes, it is fully compatible with Brembo calipers as well as major Japanese and European brake systems like Nissin, Tokico, and Magura. It supports standard M10 and M8 fittings.
What is the recommended installation torque?
During installation, you should follow the vehicle manufacturer’s specified torque value for the equivalent steel bolt size. Remember to replace the crush washers each time to ensure a reliable hydraulic seal.
Does this bolt resist damage from brake fluid?
Yes, the titanium banjo bolt is engineered specifically for brake fluid environments. It is highly optimized for DOT4 and DOT5.1 fluids, offering excellent resistance to rust, oxidation, and staining.
