Grade 5 Titanium Hex Flange Banjo Bolt with Safety Wire Holes - High-Quality China Suppliers & Factory for Motorcycles
Key Features
Six Pre-Drilled Safety Wire Holes
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.
Precision Polished Oil Passage
The internal oil passage is polished to reduce fluid resistance. This delivers smoother, more linear brake lever feel compared with OEM steel bolts.
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.
45% Lighter Than Steel Bolts
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.
Engineered for Brake Fluid Environments
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
1. Motorcycle Performance & Maintenance
Motorcycle Brake Caliper & Master Cylinder Connections
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.
Hydraulic Clutch Line Assemblies
Installed on M8 or M10 hydraulic clutch connections. It ensures secure clamping and stable sealing through repeated heat cycles for consistent clutch feel.
Brembo & Major Brake System Compatibility
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
Q
Why should I choose titanium banjo bolts over standard steel bolts?
Titanium banjo bolts are manufactured from Grade 5 Titanium (Ti-6Al-4V), offering a 45% weight reduction compared to steel. This reduces unsprung weight for improved suspension response while delivering superior corrosion resistance against brake fluids.
Q
What is the purpose of the six pre-drilled holes in the bolt head?
The pre-drilled safety wire holes allow you to secure the bolt using safety wire. This mechanical locking method prevents the bolt from backing out or loosening due to intense engine and track vibration, meeting strict racing safety regulations.
Q
Are these titanium banjo bolts compatible with Brembo brake systems?
Yes, our titanium banjo bolts are fully compatible with Brembo, Nissin, Tokico, Magura, and other major brake systems. Please verify whether your setup requires M8 or M10 thread diameter and the specific pitch (1.0mm or 1.25mm) before installation.
Q
Can I reuse my existing crush washers when installing the new bolt?
We strongly recommend replacing the crush washers every time you install or reinstall a banjo bolt. New crush washers deform properly under torque to create a reliable, leak-free hydraulic seal.
Q
How do I determine the correct torque limit for titanium banjo bolts?
You should follow the vehicle manufacturer’s specified torque settings for the equivalent steel bolt size. Do not over-torque, as titanium threads require precise installation to maintain optimal clamping force without damaging the threads.
