Grade 5 Titanium Hex Flange Banjo Bolt with Pre-Drilled Safety Wire Holes - China Suppliers & Factory Direct
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.
