Titanium Nut M10 Bi-Hex/12point Flange Metal Lock nut for Bike Motorcycle Car, disc brake, Braking system, Pitch 1/1.25/1.5mm, by Tianswer

High-temperature all-metal self-locking Grade 5 Ti-6Al-4V titanium M10 12-point (bi-hex) flange lock nuts engineered specifically for motorcycle disc brake calipers, automotive braking systems, and extreme thermal environments.

Engineering & All-Metal Locking Technology

Unlike standard nylon insert nuts that melt and fail under elevated braking friction temperatures, this all-metal lock nut utilizes a precision-engineered prevailing-torque mechanical thread distortion. The distorted top threads grip mating bolt threads under continuous mechanical tension, providing permanent vibration resistance across extreme thermal cycles up to 400°C. Precision CNC-machined from aerospace Ti-6Al-4V (Grade 5 / TC4) titanium alloy, it delivers tensile strength exceeding 950 MPa while cutting unsprung mass by roughly 45% compared to steel hardware.

Bi-Hex 12-Point Flange Design Advantages

• Compact Swing Clearance: The 12-point profile engages the socket every 30 degrees (compared to 60 degrees on standard hex nuts), allowing easy torque wrench access in cramped caliper mounts and wheel hubs.
• High Torque Transmission: Distributes tightening pressure across twelve contact flanks, virtually eliminating socket slippage and head rounding under high clamping loads.
• Integrated 20mm Load Flange: Distributes high clamping force across mounting tabs without requiring separate washers.

Key Applications

• Motorcycle Braking Systems: Radial and axial brake caliper mounting, disc rotor studs, and rear sprocket hubs (Yamaha, Honda, Kawasaki, Suzuki, Brembo setups).
• Automotive & Track Builds: Brake caliper brackets, turbocharger downpipes, exhaust manifold studs, and suspension subframe mounts.
• High-Performance Cycling: Downhill MTB and electric moto suspension linkage pivots.

Installation & Torque Recommendations

Because all-metal prevailing-torque nuts create intentional mechanical thread engagement, hand-thread the nut onto the bolt until the locking collar engages, then torque with a calibrated manual wrench. Always apply a thin coat of high-temperature copper or nickel anti-seize paste to eliminate thread galling. Never use pneumatic impact guns. Need help verifying thread pitch?
