Grade 5 Titanium Hex Flange Banjo Bolt for Motorcycle Brake & Clutch - China Suppliers & Factory Direct
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.
Installation & Maintenance Guidance
Torque Control: Follow the vehicle manufacturer’s torque for the equivalent steel bolt size when installing the Titanium Banjo Bolt. Replace crush washers each time for reliable hydraulic sealing.

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
