Grade 5 Titanium Shoulder Button Head Bolts for Motorcycles - China Suppliers & Factory Direct Bulk Purchase
Key Features
The shoulder positions components precisely, reducing movement and vibration. Lateral loads pass through the shoulder, protecting threads and keeping titanium shoulder bolts reliable under repeated stress.
The shoulder height provides a natural tightening limit, allowing clamping force to remain consistent and repeatable. This structure helps reduce surface damage caused by over tightening during installation or routine maintenance.
Made from Grade 5 titanium, these titanium shoulder bolts weigh roughly 57% less than steel fasteners, reducing unsprung mass and improving handling. PVD coating resists corrosion and maintains a high-quality look over time.
The low-profile button head fits tight spaces, preventing interference during installation or maintenance. Its consistent height ensures repeatable assembly and protects components, supporting high-end motorcycle builds and reducing costly rework.
Installation & Maintenance Guidance
Seat the Shoulder Properly. Tighten each bolt until its shoulder contacts the mounting surface. Don’t apply extra torque, as it may damage panels or nearby components.
Use Threadlocker on Brake Components. Apply medium strength threadlocker when installing Titanium Shoulder Bolts on brake discs and calipers. Follow OEM torque specs to ensure reliable performance under heat and repeated braking.

Application Scenarios
For motorcycle brake discs, the shoulder on these titanium shoulder bolts takes the shear load during hard braking rather than the threads. This helps keep the rotor properly aligned and reduces stress on the bolt in extreme braking conditions.
When fastening fairings or body panels, the shoulder serves as a depth limiter. It helps reduce hole wear caused by vibration and lowers the risk of panel damage from over tightening.
In suspension pivot points and lightweight racing disc brake connections, titanium shoulder bolts help keep parts properly positioned. They also make repeated installation more consistent when components need to be removed and refitted.
